The table describes the properties of four compounds.
Which compounds are most likely ionic?
compounds A and B
compounds B and C
compounds C and D
compounds D and A
The characteristics of the ionic bonds allows to find the results for the question about which compound are ionic is:
d) Compounds D and A.
Chemical compounds are formed by atoms linked by electrostatic forces, where one of the elements gave up some electrons and the other element acquired these electrons, the two atoms being in an ionic state, consequently the bond is strong and has several characteristics:
High melting point. It dissolves in polar solvent (water). In general they are hard and brittle solids (NaCl). In solution they are conductors of electricity.
In these characteristics, let's analyze the compounds in the table.
With the property of high melting point the compounds A and D can be ionic. According to the dissolution property all could be ionic. According to the conduction property of electricity, compounds A and D can be ionic
Let's review the different alternatives:
a) False. Compound A and B has a low melting point.
b) False. The B and C compounds have low melting points.
c) False. Compound C has a low melting point.
d) True. The two compounds meet all the characteristics of ionic compounds.
In conclusion with the characteristics of the ionic bonds we can find the results for the question about which compound are ionic is:
d) Compounds D and A are ionics.

a spacecraft that seems to be motionless in deep space is given some type of quick push. which statement describes what will happen?
An applied force applied causes a body such as the spacecraft to move. The magnitude of the force determines the change in the velocity
What will happen to the spacecraft is given by option C. from among the possible question options.
C. The spacecraft will begin to move and it will continue moving until it is stopped by an equal and opposite force
Reason:
The possible question options obtained from a similar question includes;
A. The spacecraft will move for some time then stop slowly
B. Air resistance will prevent the spacecraft from moving
C. The spacecraft will begin to move and the motion will continue until a force equal and opposite to the applied force stops it
D. The quick push will not cause the spacecraft to move, as a quick push works on Earth only
The state of the space craft = Motionless
Location of the spacecraft = Deep space
Type of force applied = Quick push
The statement that describes what will happen = Required
Solution;
Let F, represent the force applied, and let Δt be the duration of the applied force, we have;
The impulse of the force, F × Δt = m·(v₂ - v₁)
Where;
m = The mass of the spacecraft
v₁ = The initial velocity of the spacecraft = 0
v₂ = Final velocity of the spacecraft
Plugging in v₁ = 0, gives;
F × Δt = m·v₂
The space craft is given a velocity, v₂, and according to Newton's First Law of Motion, it continues moving in a straight line until another force acts on it
Therefore, the correct option is option C. The spacecraft will begin to move and the motion will continue until it is stopped by an equal and opposite force

farmer joe drives a tractor for 4 hours. his tractor is pulling a heavy plow across a rocky field. over the course of 4 hours, is the plow gaining or losing energy?
Over the course of the 4 hours for which farmer Joe's tractor is pulling the heavy plow, the plow is gaining energy by virtue of its displacement --termed the Kinetic energy.
According to the question, Farmer Joe drives the tractor for 4 hours.
However, the tractor is connected to a heavy plow and is used to pull the plow across a rocky field.
The question requires that we determine if the plow is gaining or losing energy.
In the plow's state of rest, prior to when it is connected to the tractor and pulled by the tractor; the plow possess a form of energy by virtue of its position termed the Potential energy.However, the focus of the question is during the pulling action of the tractor on the plow.
As such, the plow now has a kinetic energy by virtue of its displacement..Ultimately, the plow is gaining energy as it is being pulled by the tractor and now has Kinetic energy.

7.According to the periodic table, how many total particles are there in the nucleus of a Titanium, Ti, atom?
Answer:
there are 22 massive, positively charged, fundamental particles in the element's nucleus. Given this, the element is unquestionably titanium.
The nucleus of titanium contains 46 particles in total in which 22 protons and 26 neutrons.
What is atomic nucleus?The atomic nucleus can be described as the small and dense region containing of protons and neutrons at the center of an atom. An atom is made of a positively charged nucleus, with electrons surrounding it, bound together by electrostatic force.
Almost all of the mass of an atom is concentrated in the nucleus as the mass of electrons is negligible. Neutrons and Protons are bound together to create a nucleus by the nuclear force.
The diameter of the nucleus is about 1.70 fm for hydrogen to about 11.7 fm for uranium. Protons and neutrons are fermions, are the particles present inside the nucleus.
The titanium has 22 protons and 26 neutrons in its nucleus so it has 46 particles in its atomic nucleus.

Lorenzo pushes on a heavy crate with an applied force of 250 N at an angle of 30° below the horizontal. The force of friction opposing the applied force is 95 N. If the mass of the crate is 45 kg, what is the acceleration of the crate?
A. 0.67 m/s2 forward
B. 1.7 m/s2 forward
C. 2.7 m/s2 forward
D. 3.4 m/s2 forward
Also here are some pictures of Shoya Ishida to make your day better:3
Answer:
A. 0.67 m/s² forward
Explanation:
F applied = 250 N
Fsin30 = 250/2 = 125N
F friction= 95 N
Fnet = F app - F fri
= 125-95
= 30 N ( forward)
Fnet = m a
30 = 45 a
a= 30/45

How much energy is required to take 500g of ice at -40 degrees to water at room temperature (22 degrees Celsius)? Show work pls
Answer: Given that:
Mass (m) = 20 g = 0.02 Kg,
temperature (T₁) = -10°C = -10+273 = 263 K
temperature (T₂) = 10°C = 10+273 = 283 K
Specific heat of water (Cp) = 4.187 KJ/Kg k
We know that Heat transfer (Q) = m. Cp.( T₂ - T₁)
= 0.02 × 4.187 × (283-263)
Q = 1.67 KJ
Heat transferred is 1.67 KJ

How many electrons have been removed from a positively charged electroscope if it has a net charge of 6x10-11?
pls help !!!
How much negative charge has been removed from a positively charged electroscope if it has a charge of 7.5x10-11C?
If C is Coulombs then, −1 C is equivalent to the charge of approximately 6.242×10^18 electrons.
You already gave the answer: -7.5x10–11C
It is like asking: What colour is my white horse?
Now if you want to know how many electrons have been removed, then multiplying the number of electrons in a coulomb by the coulombs you have, you get 4.6815 x 10^8 electrons. Which is almost the same answer as before.
3.7 x 10^8 electrons are removed from a positively charged electroscope.
The magnitude of charge carried by one electron is 1.602 x 10^-19 C
From the question, we can see that the net charge on the electroscope is 6 x 10^-11 C
Given that;
6 x 10^-11 = 1.602 x 10^-19 n
Where n is the number of electrons removed from a positively charged electroscope
Therefore;
n = 6 x 10^-11/ 1.602 x 10^-19
n = 3.7 x 10^8 electrons
