Answer:
As mass increases the gravitational force increases
Explanation:
Things with mass gain a gravitational force, The bigger they are the more force, for example: the sun is the biggest so it pull us
Answer:
The valence electrons in the metal atom in the lattice structure can delocalize and move freely. The electrons are "loosely" connected with their parent atom in the metallic bond because most metals have excess electrons in their outer orbitals above the stable configuration.
Explanation:
Says google
It receives blood from the whole body. Blood from the lungs enters the heart through the pulmonary vein into the left atrium. ... - Has ventricles that has thicker walls thus more muscular than auricles generating higher pressure to pump blood over long distances.

A) covalent bond
Explanation:
Covalent bonding generally happens between nonmetals.
Answer:
0.0734 grams LiOH
Explanation:
The molarity formula looks like this:
Molarity (M) = moles / volume (L)
You are given the molarity and volume (in mL). Therefore, you can plug these values into the equation and solve for moles (after you convert from mL to L).
25 mL / 1,000 = 0.025 L
0.125 M = moles / 0.025 L
(0.125 M) x (0.025 L) = moles
0.003125 = moles
After using the molarity formula, we know that 0.003125 moles LiOH are needed to satisfy these conditions. Now, we can convert this to grams using the molar mass of LiOH. This can be determined using the values from the periodic table. Remember to write your conversion in a way that allows for the units to cancel out.
Molar Mass (LiOH) = 6.941 g/mol + 16.00 g/mol + 1.008 g/mol
Molar Mass (LiOH) = 23.499 g/mol
0.003125 moles 23.499 g
------------------------ x ------------------- = 0.0734 grams LiOH
1 mole
