Hydrogen peroxide rapidly decomposes to water and oxygen. If the water is appearing at a rate of 2.0 M/s, what is the rate of th
balu736 [363]

Answer:

Rate of reaction = 2.0 M/s

Explanation:

2H2O2(g) --> 2H2O(g) + O2(g)

Rate of formation of H2O = 2.0 M/s

Rate of reaction can be measured using multiple techiques and parameters like volume, pressure etc.

Among these techniques is the measurement of appearance of products.

This means we have;

Rate of reaction = Rate of appearance of product

Hence;

Rate of reaction = 2.0 M/s

How many grams of potassium bromide, KBr, are in 100mL of a 0.50 M solution?
VMariaS [17]

Answer:

5.95g

Explanation:

1 dm^{3} = 1000 mL

∴ 100 mL = 100 ÷ 1000 = 0.1 dm^{3}

Volume = <u>0.1 </u>dm^{3}<u />

Concentration = <u>0.5 M</u>

Concentration = \frac{No. of moles}{volume}

0.5 = \frac{x}{0.1}

No. of moles = 0.5 x 0.1 = <u>0.05 moles</u>

No. of moles = \frac{mass}{mass. in. 1. mole}

Mass in 1 mole of KBr = 39 + 80 = 119g (39 is the mass of potassium and 80 is the mass of bromine)

0.05 = \frac{x}{119}

x = 119 × 0.05 = 5.95g

STALIN [3.7K]

what is Maximum possible products?

Although Minimum Viable Product strategies are effective for startups, they presuppose you have no limitations. However, in an MPP universe, your limitations serve to focus you rather than to thwart you. Instead than conceptualizing ideas for the future, they require you to consider how well you can meet your clients' wants inside a specific situation that now exists.

Photobox will introduce countless new product lines that are only modifications of current products. For instance, a bowl could be printed as a dog bowl or a cereal dish for kids. The tech stack doesn't need to be altered, and customization yields the highest return on investment for the product.

Which equation using element symbols correctly describes the reaction: "One molecule of methane plus two molecules of diatomic o
kiruha [24]

Answer:

C. CH₄+2O₂ →2H₂O+CO₂

Explanation:

This is a popular combustion reaction.

            C. CH₄+2O₂ →2H₂O+CO₂

In combustion, hydrocarbons burn in the presence of oxygen gas and they produce water and carbon dioxide only. The process is accompanied with the release of energy.

We simply say for the above reaction that:

           One molecule of methane(CH₄) reacts with two molecules of oxygen gas(O₂) to produce two molecules of water(H₂O) and one molecule of carbon dioxide only
