An octopus swims 7 km at a speed of 3 km/hr.How long does it take in hours and minutes?

Answer:

Phosphorus ( white) us highly reactive and ignites at about 30°C when exposed to moist air

Answer:

Explanation:

I'm not sure what is being asked, not the units of "1.5."  I don't know of potassium "ioxicide."  Was "dioxide" intended?

I'll assume the question is "What is the concentration, in Molar, of 1.5g of potassium dioxide in 150cm^3 of water (150cm^3 is 150 ml).

The molar mass of K2O, potassium dioxide, is 94.2 g/mole.  1.5g is (1.5g/94.2 g/mole) or 0.0159 moles of K2O.  The definition of Molar is moles/liter.  So take the moles of K2O and divide by the liters, which is 0.150L in this case.

(0.0159 moles K2)/0.150 L  = 0.106 M K2O

Explanation:Compounds between Nonmetals and Nonmetals

Compounds that consist of a nonmetal bonded to a nonmetal are commonly known as Molecular Compounds, where the element with the positive oxidation state is written first. In many cases, nonmetals form more than one binary compound, so prefixes are used to distinguish them.

# of Atoms 1 2 3 4 5 6 7 8 9 10

Prefixes Mono- Di- Tri- Tetra- Penta- Hexa- Hepta- Octa- Nona- Deca-

the compounds are covalent, not ionic

Answer: 116.12 g/mol

Explanation:

The molecular mass of a formula unit of dimethylglyoxime is calculated as 116 g/mol.

The molecular mass can be given as the sum of the mass of each element in the formula unit of the compound.

The dimethylglyoxime is the compound with molecular formula, [tex]\rm C_4H_8N_2O_2[/tex].

The mass of each element in the compound is:

Substituting the mass in the formula unit of the compound as:

[tex]\rm C_4H_8N_2O_2=4(carbon)+8(hydrogen)+2(nitrogen)+2(oxygen)\\ C_4H_8N_2O_2=4(12)+8(1)+2(14)+2(16)g\\ C_4H_8N_2O_2=116\;g[/tex]

The molecular mass of dimethylglyoxime is 116 g/mol.

Explanation:

An atom ion and isotope of an element have in common that both have the same number of protons but they have different numbers of neutrons.

An ion is a charged atom while an isotope is the atoms of an element with the same atomic number but different atomic mass.

For example; Mg2+ is the ionic form of Magnesium while C-12 and C-14 are isotopes of carbon.

Here the ion of an atom will have a different charge but the same mass.

Also The isotope of an atom will have a different mass.

The number of protons V/S the more general atom, an ion has a different number of electrons, and an isotope, a different number of neutrons.

Hence atom ion and isotope of an element have in common that both have the same number of protons but they have different numbers of neutrons.

Answer:

In this reaction, potassium atoms lose electrons to form positively-charged potassium ions (oxidation) and iodine atoms gain electrons to form negatively-charged iodide ions (reduction).

Explanation:

pls mark as brainliest

In this process, iodine atoms get electrons to produce negatively charged iodide ions, whereas potassium atoms lose electrons to form positively charged potassium ions. Oxidation and reduction takes place.

Redox reactions include a change in the oxidation state of the substrate. Similar to how reduction is the acquisition of electrons while oxidation is the loss of electrons or an increase in the oxidation state.

An oxidation process takes place when oxygen interacts with a substance or an element. Another way to think of oxidation is as the process of removing hydrogen from the species of reactants. Molecule, atom, or ion oxidation is the process of losing electrons.

Because they generate new functional groups in molecules or alter existing functional groups, oxidation processes are crucial in the synthesis of organic substances.

Thus, the iodine atom also experiences a change. The iodide atom gets one electron during the reaction with potassium, leaving it with eight electrons at its outer energy level.
