For cm to m, you need to divide by 100 to get m:
26cm/100= 0.26m

For hr to min, you need to multiply by 60 to get min:
4hr x 60= 240min

For km to m, you need to multiply by 1000 to get m:
3.25km x 1000= 3250m

For ft to in, you need to multiply by 12 to get in:
5ft x 12=60in

So we have:
0.26m
240min
3250m
60in

At a certain temperature the rate of this reaction is first order in HI with a rate constant of 0.0632 s
kirza4 [7]

Answer:

28.037\ \text{s}

Explanation:

[A]_0 = Initial concentration = 1.28 M

[A] = Final concentration = 0.17[A]_0

k = Rate constant = 0.0632 s

t = Time taken

For first order reaction we have the relation

kt=\ln\dfrac{[A]_0}{[A]}\\\Rightarrow t=\dfrac{\ln\dfrac{[A]_0}{[A]}}{k}\\\Rightarrow t=\dfrac{\ln\dfrac{[A]_0}{0.17[A]_0}}{0.0632}\\\Rightarrow t=28.037\ \text{s}

Time taken to reach the required concentration would be 28.037\ \text{s}.

Use the atom builder interactive to identify each nucleus. Two protons represented as purple spheres and one neutron represented
aleksandr82 [10.1K]

Answer:

\frac{3}{2}He

\frac{6}{2} He

\frac{7}{4}Be

\frac{3}{1} H

\frac{6}{4}Be

\frac{7}{3} Li

Explanation:

In the first nucleus we are told that there are two protons and one neutron. Let us remember that the mass number = number of protons + number of neutrons.

This implies that, for the first specie the mass number is 3, for the second specie the mass number is 6 and the third specie has a mass number of 7 and so on. The mass number is indicated as a superscript.

The atomic number is the number of protons in the nucleus of the atom and helps us to identify the atom. It is always written as a subscript as shown.
