Answer:
See Explanation
Explanation:
Given
2500 meters
200 grams
Required
How do they compare?
You can't compare these two measurements in terms or size, units and measurements because they measure two different quantities
2500 meters measures length or distance
while
200 grams measures mass of objects
Answer: 1.5mol NH3
Explanation: 1N2+3H2= NH3
0.5 mol N2x 3NH3/1molN2= 0.5x3= 1.5mol NH3
Answer:
<em>(H30+)= 1x10^-6 M</em>
Explanation:
Both pH and pOH have a relationship to belonging to the same aqueous solution: the expression of the Kwater (ionic product of the water Kw) is used:
1x 10-8 mol/L equals to1x10-8 M
(H3O+) x (OH-) = 1x10^-14
(H30+)x 1x 10^-8 =1x10^-14
(H30+)= 1x10^-14/1x 10^-8
<em>(H30+)= 1x10^-6 M</em>
Answer:
• Hydrogen and oxygen atoms
Explanation:
Hydrogen and oxygen are nonmetals. They are most likely to share electrons and form a covalent bond.
A is wrong. Gold is a metal, so it will form metallic bonds.
O is wrong. Neon is a noble gas. It has a complete octet, so it is unlikely to form covalent bonds.
D is wrong. Mg is a metal, and Br is a nonmetal. They are more likely to form ionic bonds.
