Answer:

Ba(OH)₂(aq) + 2HCl(aq) → BaCl₂(aq) + 2H₂O(l).

Explanation:

1 mol of Barium Hydroxide with 2 moles of hydrochloric acid  to produce 1 mol of barium chloride and 2 moles of water according to the equation:

<em>Ba(OH)₂(aq) + 2HCl(aq) → BaCl₂(aq) + 2H₂O(l). </em>

If i have 8 L of 0.25 M solution, how many miles of MgCl2 are present
qaws [65]

Answer:

2 moles

Explanation:

The following were obtained from the question:

Molarity = 0.25 M

Volume = 8L

Mole =?

Molarity is simply defined as the mole of solute per unit litre of solution. It is represented mathematically as:

Molarity = mole of solute/Volume of solution.

With the above equation, we can easily find the number of mole of MgCl2 present in 8 L of 0.25 M MgCl2 solution as follow:

Molarity = mole of solute/Volume of solution.

0.25 = mole of MgCl2 /8

Cross multiply to express in linear form

Mole of MgCl2 = 0.25 x 8

Mole of MgCl2 = 2 moles

Therefore, 2 moles of MgCl2 are present in 8 L of 0.25 M MgCl2 solution

How many bonding and non-bonding electron pairs are found in the BF3 molecule?​
Contact [7]

Answer:

MARK AS BRAINLIEST

Explanation:

Boron trifluoride only has six valence electrons and is one of the relatively rare second period covalent molecules that disobeys the octet rule. There are three bonded groups and so no lone pairs. Six electrons implies three electron pairs and therefore a trigonal geometry.
