Answer:

c and o

Explanation:

Carbon and Oxygen cannot react to form an ionic compound because the two elements are non-metals.

To form an ionic bond, a metal combines with a non-metal through electrostatic attraction of oppositely charged ions.
This leads the bond formation.
Carbon is a non-metal, with oxygen, they will prefer to form a covalent bond where they share their electrons

If a 1.00 mL sample of the reaction mixture for the equilibrium constant experiment required 32.40 mL of 0.258 M NaOH to titrate

andrey2020 [161]

Answer:

The concentration of acetic acid is 8.36 M

Explanation:

Step 1: Data given

Volume of acetic acid = 1.00 mL = 0.001 L

Volume of NaOH = 32.40 mL = 0.03240 L

Molarity of NaOH = 0.258 M

Step 2: The balanced equation

CH3COOH + NaOH → CH3COONa + H2O

Step 3: Calculate the concentration of the acetic acid

b*Ca*Va = a*Cb*Vb

⇒with b = the coefficient of NaOH = 1

⇒with Ca = the concentration of CH3COOH = TO BE DETERMINED

⇒with Va = the volume of CH3COOH = 1.00 mL = 0.001L

⇒with a = the coefficient of CH3COOH = 1

⇒with Cb = the concentration of NaOH = 0.258 M

⇒with Vb = the volume of NaOH = 32.40 mL = 0.03240 L

Ca * 0.001 L = 0.258 * 0.03240

Ca = 8.36 M

The concentration of acetic acid is 8.36 M

Of the below gases, which would deviate most from ideal gas behavior? CO O2 NH3 SF4

Vlad [161]

Answer:

For gases such as hydrogen, oxygen, nitrogen, helium, or neon, deviations from the ideal gas law are less than 0.1 percent at room temperature and atmospheric pressure. Other gases, such as carbon dioxide or ammonia, have stronger intermolecular forces and consequently greater deviation from ideality.

What is the name of the ability to use up energy in one second

Savatey [412]

Answer:

Work

Explanation:

Work is defined as the ability to use energy in one second and its SI unit is same as energy that is joule.

Work refers to the energy utilized to displace an object over a distance by an external force in one direction and in given time period which can be one second as well.

Hence, the correct answer is "work".
