scoray [572]

Answer:

The answer to your question is HCl + NaOH ⇒ NaCl + H₂O

Explanation:

Data

Double displacement reaction

Balanced chemical reaction

HCl + NaOH ⇒ NaCl + H₂O

Reactants Elements Products

1 Chlorine (Cl) 1

1 Sodium (Na) 1

2 Hydrogen (H) 2

1 Oxygen (0) 1

As we can see, the reaction is balanced and the coefficients of all reactants and products are 1, but the number is not written in a balanced reaction.

This equation shows a ____ refer to this summary equation of photosynthesis to complete the sentences about chemical bonds and r

coldgirl [10]

The balanced chemical equation representing the process of photosynthesis is:

$6 CO_{2} +12H_{2}O-->C_{6}H_{12}O_{6}+6O_{2}$

The reactants in the process of photosynthesis are $CO_{2}$ and H $H_{2}O$ and the products of the reaction are glucose $C_{6}H_{12}O_{6}$ and oxygen $O_{2}$ . Oxygen is the nonpolar covalent gas which is released in the process of photosynthesis. The reactant $CO_{2}$ is a nonpolar covalent gas while the other reactant water $H_{2}O$ has polar covalent O-H bonds.

In the balanced chemical equation, the number of each type of element must be equal on both sides of the reaction.

Find the pH of HCl with a concentration of 0.00006M<br> Round to the nearest whole number

Tpy6a [65]

Answer:

4.22

Explanation:

pH stands for potential hydrogen. The letter “p” denotes potential and the letter “H” denotes hydrogen.

pH helps to find the acidity or alkalinity of an aqueous solution.

The number of hydrogen ions (protons) present in a solution is determined by the pH scale.

A pH greater than 7 makes the water more alkaline and a pH less than 7 makes the water more acidic.

$pH=-\log [H^+]=-\log [0.00006]=4.22$

Cerrena [4.2K]

Answer:

Extensive properties vary with the amount of the substance and include mass, weight, and volume. Intensive properties, in contrast, do not depend on the amount of the substance; they include color, melting point, boiling point, electrical conductivity, and physical state at a given temperature.
