Answer:

Synthesis reaction

Explanation:

To know which option is correct, it important that we know what each option represents.

Synthesis reaction is a reaction in which two different elements react to form a single compound. For example

X + Y —> XY

Decomposition reaction is a reaction in which a compound splits into two or more simpler substance. For example

XY —> X + Y

Single Replacement reaction is a reaction in which one element replaces or displaces another element from a compound. For example

X + YZ —> XZ + Y

Double Replacement reaction is a reaction in which the parts of two ionic compounds exchange their ions to form a new compound. For example

WX + YZ —> WZ + YX

Now, considering the equation given above i.e

P + O₂ —> P₄O₁₀

We can see that P and O₂ reacted to produce a new compound (i.e P₄O₁₀).

Thus, the reaction is a synthesis reaction because two different elements (i.e P and O₂) reacted to form a single compound (i.e P₄O₁₀).

Please help ASAP! I’m lost right now.

Chromium is strange because it moves on to the 4s orbital instead of filling the 3d orbital with that last electron. Tricky.

Mark as brainliest if this helped! :)

You find a compound composed only of element X and chlorine and you know that the compound is 13.10% X by mass. Each molecule of

8_murik_8 [283]

Answer:

Explanation:

So, the formula for the compound should be:

$XCl_{6}$

Now we assume that we have 1 mol of substance, so we can make calculations to know the molar mass of element X, as follows:

$M_{Cl}=35.45g/mol\\$

So we have that 6 moles weight 212.7g, and we can make a rule of three to know the weight of compound X:

$212.7g\rightarrow 86.9\%\\x\rightarrow 13.1\%\\\\x=\frac{212.7g*13.1}{86.9} =32.06g$

As we used 1 mol, we know that the molar mass is 32.06g/mol

So the element has a molar mass of 32.06 g/mol and an oxidation state of +6, with this information, we can assure that the element X is sulfur, so the compound is $SCl_{6}$

Hydrogen is an element with two naturally occurring isotopes: 2 H and 3 H. This means that 2 H, which has a mass number of 2, ha

Dmitry_Shevchenko [17]

Answer:

TRUE.

Explanation:

Mass Number is the sum of protons and neutrons present in the nucleus of an atom. Isotopy is a phenonmenon that occurs when atoms of same elements have different mass number (Number of neutrons).

2H isotope has 1 proton and 1 neutron.

3H isotope has 1 proton and 2 neutrons.

This meeans 2H isotope has fewer neutrons when compared to the 3H isotope. The correct option is TRUE.
