1. The reaction is a neutralization reaction

2. The reactant added to the water causes an acid reaction

3. The reactant added to the water causes a base reaction

4. The molarity of the solution is 0.025 M

<h3>What is a neutralization reaction? </h3>

This is a reaction involving an acid and a base which result in the formation of salt and water only

HF + NaOH –> H₂O + NaF

The reaction above indicates neutralization since the reaction produces water (H₂O) and salt (NaF) only

<h3>What is an acid? </h3>

An acid is a substance which dissolves in water to produce hydronium ion H₃O⁺

3HI + 2H₂O —> 2H₃O⁺ + 3I¯ + H⁺

The reaction above is an acid reaction since it produces H₃O⁺

<h3>What is a base? </h3>

A base is a substance which dissolves in water to produce hydroxide ion OH¯

2CH₃COO¯ + H₂O —> CH₃COO¯ + OH¯ + CH₃COOH

The reaction above is a base reaction since OH¯ is produced.

<h3>How to determine the molarity </h3>
  • Mole = 0.05 mole
  • Volume = 2 L
  • Molarity =?

Molarity = mole / Volume

Molarity = 0.05 / 2

Molarity = 0.025 M

What is the speed of light?can a object move in speed of light?​
timurjin [86]

Answer:

The speed of light is the speed at which light travels. No, an object cannot move at the speed of light.  

Explanation:

The speed of light is 186,000 miles per second. An object with mass cannot move at the speed of light since it would take an infinite amount of energy to achieve that velocity, since only massless particles can travel at the speed of light. Also, you would have to factor in air friction, meaning even if an object were to reach such high speeds, it would instantly disintegrate.

A reading shows a pressure measurement of 43 in. Hg. What is the equivalent pressure in psi? A. 5.73 psi B. 2223.13 psi C. 26.32
oksian1 [2.3K]
43 inHg = 43 inHg*2.54cm/in = 109.22cmHg * 10 mm/cm = 1092.2 mmHg


14.7 psi = 760 mmHg

1092.2mmHg * 14.7psi / 760 mmHg = 21.13 psi

Answer: option D. 21.13 psi

What is true of tectonic plates?
kupik [55]

Answer:

Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core. The plates act like a hard and rigid shell compared to Earth's mantle. ... The lithosphere includes the crust and outer part of the mantle.

Over-the-counter hydrogen peroxide solutions are 3% (w/v). What is this concentration in moles per liter?
Marina CMI [18]
<span>1 ml of water weighs 1 gram so 1 liter (1000 ml) weighs 1000 grams. A 3% solution (3% = 0.03) of hydrogen peroxide (w/v) would contain 1000 grams x 0.03 or 30 grams. The chemical formula of hydrogen peroxide is H2O2 and a mole weighs 34.0147 grams/mole. So 30 grams of H2O2 divided by 34.0147 grams/mole equals 0.88 moles of H2O2. The concentration of a 3% (w/v) hydrogen peroxide solution therefore contains 30 grams of H202 (or 0.88 moles of H202) per in a liter of water (or 1000 grams H20) would thus be 0.88 moles H2O2 per liter (0.88 moles H2O2/l) .</span>
