Answer:
9.7 ml
Explanation:
Molarity = 2.5 M
Mass = 0.97g
Volume = ?
The relationship between these quantities is;
Molarity = Number of moles / Volume
Number of moles = Mass / Molar mass
Molar mass of NaOH = 40g/mol
Number of moles = 0.97 / 40 = 0.02425 mol
Volume = Number of moles / Molarity = 0.02425 / 2.5 = 0.0097 L
1000 ml = 1L
x = 0.0097 L
x = 0.0097 * 1000 = 9.7 ml
1. the amount of heat that it would take would be :
5.1 x 10^4 J
2. I think the substance would be : Iron
3. the amount of heat required would be :
1.13 x 10^4 kJ
Hope this helps

Option C.When a neutral hydrogen atom loses an electron, a positively-charged
.
<h2>Explanation:
</h2>
- When a neutral hydrogen atom loses an electron a positively charged particle must remain.
- Proton is a positive charge of +1 e charge with a mass that is slightly less than that of a neutron.
- Ernest Rutherford discovered that a atom must have a concentrated positive charge at the center that contains most of the atom's mass. He stated that the nucleus contained a positive charge the proton. And the weight of a proton is 1837 times heavier than the weight of the electron.
Result: Losing of an electron by hydrogen lefts a positive charge i.e proton.
Answer:
macro-evolution
