Answer:

Explanation:

An isotope is an atom that has a different number of neutrons than the standard for that atom.

1)Nitogen -14 has 7 protons in the nucleus for its an isotope of nitrogen which has an atomic number of 7.

2)Now we need to find the number of neutrons. This is implied in the name of the isotope whereby the protons and neutrons add up to its atomic number. So

(14-7 protons= 7 neutrons.)

So it has 7 neutrons.

Mariana [72]

Answer:

"500 Joule/sec" is the right answer.

Explanation:

The given values are:

Force,

F = 1000 N

Velocity,

s = 10 m

Time,

t = 20 s

Now,

The power will be:

= $\frac{Force\times Velocity}{Time}$

On putting the values, we get

= $\frac{1000\times 10}{20}$

= $\frac{10000}{20}$

= $500 \ Joule/sec$

Answer:

0.571 mol

Explanation:

Given data:

Number of moles of NaHCO₃ = 0.571 mol

Number of moles of CO₂ produced = ?

Solution:

Chemical equation:

NaHCO₃ + C₃H₆O₃ → CO₂ + C₃H₅NaO₃ + H₂O

Now we will compare the moles of CO₂ with NaHCO₃ from balance chemical equation.

NaHCO₃ : CO₂

1 : 1

0.571 : 0.571

So number of moles of CO₂ produced are 0.571.
