Pls help me on question 30 I don't know how to do it

Answers

Answer 1

Answer: The rate law for a reaction that is first order in both reactants is Rate=k[A][B]. Therefore to find the rate you plug in the values you are given to get the equation rate=0.5×0.0183×0.0168 to get Rate=1.54×10⁻⁴ mol/Ls.

I hope this helps. Let me know in the comments if anything is unclear.

Which of the following elements would be considered a nonmetal?fluorine (#9)
silicon (#14)
cobalt (#27)
sodium (#11)

Answers

The element among the list that is not a metal there is the element fluorine.

What is a nonmetal?

A nonmetal is an element that occur towards the right hand side of the periodic table and does not have the general properties that are attributed to metals such as the ability to react with acids.

The element among the list that is not a metal there is the element fluorine.

Marshall determines that a gas has a gauge pressure of 276 kpa what's the absolute pressure of the gas

Answers

A gauge records the pressure over atmospheric pressure (0kpa on the gauge is actually the atmospheric pressure and a reading of 276kpa is 276kpa over atmospheric pressure). That means that means that to find absolute pressure you just add atmospheric pressure (around 1atm (101kpa)) to 286kpa to get 387kpa. I hope this helps.

Which statement describes a chemical property of aluminum?(1) Aluminum is malleable.
(2) Aluminum reacts with sulfuric acid.
(3) Aluminum conducts an electric current.
(4) Aluminum has a density of 2.698 g/cm3 at STP.

Answers

The correct answer as to which statement describes a chemical property of aluminum would be that it reacts with sulfuric acid.

There are two properties of every substance - physical and chemical properties.

Physical properties refer to the characteristics that can be observed without altering the substance while chemical properties refer to the characteristics of undergoing chemical changes in reactions.

Physical properties include color, boiling and melting point, hardness etc., while chemical properties include reactivity, toxicity, flammability, etc.

All the options have to do with physical properties of aluminum except its reactivity with sulfuric acid. The equation of reaction is as follows:

Al + H2SO4 ---> Al2(SO4)3 + H2

Which balanced equation represents a chemical change?(1) H2O(l) + energy → H2O(g)
(2) 2H2O(l) + energy → 2H2(g) + O2(g)
(3) H2O(l) → H2O(s) + energy
(4) H2O(g) → H2O(l) + energy

Answers

The answer is B because energy was added to 2H2O in order to produce a chemical change of 2H2 and 02 seperately.

Final answer:

The balanced equation that represents a chemical change is 2H2O(l) + energy → 2H2(g) + O2(g).

Explanation:

The balanced equation that represents a chemical change is (2) 2H2O(l) + energy → 2H2(g) + O2(g). In this equation, we see the reactant, water (H2O), being converted into two separate products, hydrogen gas (H2) and oxygen gas (O2), with the addition of energy. This indicates a chemical change taking place where new substances are formed.

The radioisotope radon-222 has half-life of 3.8 days. how much of a 73.9-g sample of radon-222 would be left after approximately 23 days?

Answers

This can be solved by the equation:

A = Aoe^(-ln2/t)T
where Ao is the initial amount of the substance ( 73.9-g sample of radon-222 ), t is the half-life time (3.8 days) and T is the time elapsed. Plugging in the values in the equation, the substance left is 1.11g.
