how many grams of bacl2 are formed when 35.00 ml of 0.00237 m ba(oh)2 reacts with excess cl2 gas?
Explanation:
Answer:
0.0071g
Explanation:
From the question, we know that the molarity of the BaCl2 is 0.00237M. This means there are 0.00237 moles in 1dm^3 or 1000cm^3 of solution.
We also know that 35ml of the BaCl2 reacted. Here, we need to calculate the number of moles in 35.7ml of BaCl2.
This is calculated as follows;
0.00237moles are in 1000cm^3
Thus x moles will be present in 35ml ( we should note that cm^3 is same as ml)
X = (0.00237 × 35) ÷ 1000 = 0.00008295 moles.
From the reaction equation, we can see that 2 moles of BaCl2 yielded 1 mole of Ba(OH)2.
This means 0.00008295mole of BaCl2 will yield 0.00008295 ÷ 2 = 0.000041475 moles of Ba(OH)2.
To calculate the mass of Ba(OH)2 formed, we simple multiply the number of moles yielded by the molar mass of Ba(OH)2.
Molar mass of Ba(OH)2 = 137 + 2(17)
= 171g/mol
Mass = 171 × 0.000041475 = 0.007092225g

on a test flight a rocket with mass 400 kg blasts off from the surface of the earth. the rocket engines apply a constant upward force f until the rocket reaches a height of 100 m and then they shut off.
Answer:
F= 11.76 kn
Explanation:
The rocket engines apply a constant upward force of 15680 N.
What is force?Force can be said as the amount of pressure that is applied ob an object. One can easily determine the mass and the velocity to find the force that is applied to an object.
Gravitational acceleration which will be represented by g = 9.8 m/s2
Mass of the rocket which will be represented by M = 400 kg
Constant upward force that is applied on the engine of the rocket which will be represented by F
The height through which engines accelerate the upward force upon the rocket will be represented by h = 100 m
Work done by the engine which will be represented by W
W = Fh
Maximum height well above the surface, this data will represent the rocket reaches which will be represented by H
The work completed with the help of the engine on the rocket is equal to the potential energy gained with respect to maximum height.
W = MgH
Fh = MgH
F(100) = (400)*(9.8)*(400)
F = 15680 N

The average rate of change of the function y = cos(2x) over the interval (0, π/2) is [tex] \frac{-4}{\pi}[/tex]
The average rate of change over a given interval is defined thus :
[tex] R = \frac{f(b) - f(a)}{b - a}[/tex] Where a and b are the interval valuesAt a = 0 :
f(0) = cos(2(0)) = Cos 0 = 1At b = π/2 :
f(π/2) = cos(2(π/2)) = Cos π = - 1Hence,
[tex] \frac{f(b) - f(a)}{b - a} = \frac{-1-1)}{\frac{\pi}{2} - 0} = \frac{-2}{\frac{\pi}{2}} = \frac{-4}{\pi} [/tex]

The RNA molecule is a single-strand molecule that contains uracil, adenine, cytosine and guanine. The mRNA is a special type of RNA that takes the original code out of the nucleus and translates it into proteins.
During transcription, a specific DNA fragment (e.g., a gene) localized in the cell nucleus is used as a template to encode a complementary single-strand RNA sequence, usually a messenger RNA (mRNA) sequence.
Subsequently, the mRNA travels to the cytoplasm where it is then used a template to encode a polypeptide chain (i.e., a protein) in the ribosomes by a process called translation.
In RNA, Thymine bases are replaced by Uracil bases.
In conclusion, the RNA molecule is a single-strand molecule that contains uracil, adenine, cytosine and guanine. The mRNA is a special type of RNA that takes the original code out of the nucleus and translates it into proteins.

The measure of angle CAB in the parallelogram described is 34°.
Given :
∠CAB = 21°
∠ CAB = ∠ACD (Alternate interior angles)
∠ACD = 21°
∠DAC + ∠ADC + ∠ACD = 180° (Sum of interior angles of a triangle)
∠DAC + 125° + 21° = 180°
∠DAC = 180° - 146°
