Only HF and HMnO₄ are acids and all others are base.

When the given substances are put in water, they break apart to give H⁺ or OH⁻ ions. Only HF and HMnO₄ will give H⁺ ions and others will give OH⁻ ions. It is these ions which give a substance its acidic or basic nature. All the substances that give H⁺ ions are acidic in nature. The others that give OH⁻ ions are basic in nature.

Help please<br> It’s kinda urgent
user100 [1]

Answer:

a = - 50 [m/s²]

Explanation:

To solve this problem we simply have to replace the values supplied in the given equation.

Vf = final velocity = 0.5 [m/s]

Vi = initial velocity = 10 [m/s]

s = distance = 100 [m]

a = acceleration [m/s²]

Now replacing we have:

(0.5)^{2}-(10)^{2} = 2*a*(100)\\0.25-10000=200*a\\200*a=-9999.75\\a =-50 [m/s^{2} ]

The negative sign of acceleration means that the ship slows down its velocity in order to land.

What type of reaction feels cold to the touch? A. Endothermic, because energy is being released into the surroundings B. Endothe
Crazy boy [7]

Answer:

D. Exothermic, because energy is being absorbed from the surroundings

Explanation:

This is true about the Exothemic reaction due to the fact that, the reaction occurs outside the body. During this reaction, the energy being absorbed <em>from the surrounding environment will hit the body surface thereby creating the coldness due to the heat given out from the body  being minimal.</em>
