It is B (1,1,2) because when you plug those numbers in, there are the same amount of elements in the reactant and product, just rearranged as the format A+B <span>→ AB, because this is a synthesis reaction.</span>

Answer: The correct option is B.

Explanation: We are given an unbalanced chemical equation, so to find out the actual coefficients for the reaction, we need to balance it.

Balancing a chemical equation, we get

$Cl_2O_5+H_2O\rightarrow 2HClO_3$

The coefficients for the reaction as seen from above equation are 1, 1, 2.

The correct option is B.

At 100.0∘C, the ion product of water is 5.13×10−13. What is the concentration of hydroxide ions at this temperature? Your answer

Trava [24]

Answer: The concentration of hydroxide ions at this temperature is $7.16\times 10^{-7}$

Explanation:

When an expression is formed by taking the product of concentration of ions raised to the power of their stoichiometric coefficients in the solution of a salt is known as ionic product.

The ionic product for water is written as:

$K_w=[H^+][OH^-]$

$5.13\times 10^{-13}=[H^+][OH^-]$

As $[H^+]=[OH^-]$

$5.13\times 10^{-13}=x^2$

$x=7.16\times 10^{-7}$

The concentration of hydroxide ions at this temperature is $7.16\times 10^{-7}$

antoniya [11.8K]

Answer:

The data are inadequate.

Explanation:

In the given question, there are fifteen players on the team.

But Diana and Kinsey survey only the five players on the starting lineup about their favorite mascot.

Based on only a few players out of the total number of players, both Diana and Kinsey can't choose a mascot for the basketball team.

So, the data are inadequate.

8. Given the balanced chemical equation Br2 + 2 NaI -> 2 NaBr + I2 How many moles of sodium bromide (NaBr) could be produced

bezimeni [28]

Since we are already given the balanced equation:

$Br_{2}+2NaI$ → $NaBr+I_{2}$

We can derive the molar ratios as: 1:2:1:1

That being said, we are given 0.172 moles of bromine ( $Br_{2}$ ), so it has a ratio of 1:1 with sodium bromide ( $NaBr$ ).

So we can take from that ratio, that when 0.172 moles of bromine are used, we are, in turn, going to get 0.172 moles of sodium bromide produced.

Varvara68 [4.7K]

Answer:

Anhydride, any chemical compound obtained, either in practice or in principle, by the elimination of water from another compound. Examples of inorganic anhydrides are sulfur trioxide, SO3, which is derived from sulfuric acid, and calcium oxide, CaO, derived from calcium hydroxide

Explanation:

<h3><em><u>examples</u></em><em><u>.</u></em></h3>

1)acid anhydride.

2)basic anhydrides.

<h3><em><u>reactions</u></em><em><u>. </u></em></h3>

1)reaction with water
