Select all that identify a covalent bond.

1 answer:

8 0

Heres the best help i can give you There is a couple different ways to determine if a bond is ionic or covalent. By definition, an ionic bond is between a metal and a nonmetal, and a covalent bond is between 2 nonmetals. So you usually just look at the periodic table and determine whether your compound is made of a metal/nonmetal or is just 2 nonmetals

Container A holds 717 mL of ideal gas at 2.50 bar . Container B holds 179 mL of ideal gas at 4.30 bar . If the gases are allowed

Nesterboy [21]

Answer:

Pressure gas A

using boyles law

$p1}$ $V_{1}$ = $P_{2}$ V2

V2 = 717ml + 179 ml

= 896ml

∴ $P_{2}$ = 2.50 × 717ml/896ml

= 2.0 bar

Pressure B

P2 = 4.30 bar× 179ml/896ml

= 0.859bar

ptotal = $P_{A}$ + $P_{B}$

= 2.0 bar + 0.859 bar

= 2.859 bar

Explanation: Using Daltons law of partial pressure,the pressure is independently of each other when the gas is exerted.where we can use daltons law to find the pressure of each gas separately when it expands into the total volume in two containers.

A solution has a pH = 4.63. What is the [H3O+] concentration?

LUCKY_DIMON [66]

Explanation:

The pH of a solution can you be found by using the formula

$pH = - log [ { H_3O}^{+}]$

Since we are finding the [H3O+] , substitute the value of the pH and find it's antilog

We have

$4.63 = - log[ { H_3O}^{+}] \\ [ { H_3O}^{+}] = {10}^{ - 4.63} \\ \\ = 2.344 \times {10}^{ - 5} mol {dm}^{ - 3}$

Hope this helps you

What is the difference between ionic and covalent bonding?

mr Goodwill [35]

In an ionic bond, one atom essentially donates an electron to stabilize the other atom. The atoms in an ionic bond have different electronegativity values from each other.

While in a covalent bond, the atoms are bound by shared electrons and the electronegativity values are the same.
