Answer:

Sodium + Water = Sodium Hydroxide + Dihydrogen

Explanation:

eaction of sodium with water

Sodium metal reacts rapidly with water to form a colourless solution of sodium hydroxide (NaOH) and hydrogen gas (H2). The resulting solution is basic because of the dissolved hydroxide. The reaction is exothermic.

What is the relationship between density and viscosity?

PolarNik [594]

Answer:There is no relationship between the viscosity and density of a fluid. While viscosity is the thickness or thinness of a fluid, density refers to the space between its particles. However, both properties are affected by temperature. When a fluid is heated, its particles move far apart, and it also becomes less viscous.

Calculate the pH of a solution that has a [OH−] of 2.6 × 10^−6 M.

TiliK225 [7]

Answer:

A. 8.4

Explanation:

[OH⁻] = 2.6 × 10⁻⁶ Take the negative log of each side

-log[OH⁻] = pOH = 5.59 Apply the pH/pOH relation

pH + pOH = 14.00 Insert the value of pOH

pH + 5.59 = 14.00 Subtract 5.59 from each side

pH = 14.00 -5.59 = 8.41

A beaker with water and the surrounding air are all at 24°C. After ice cubes are placed in the water, heat is transferred from:

xxTIMURxx [149]

(3) the water to the ice cubes
This is so because the ice cubes are colder compared to their surrounding objects.
They absorb the heat from the water, cooling it, therefore vanishing(melting).

Each of the following reactions is incomplete. Match each of the following particles with the correct reaction in order to compl

kiruha [24]

Answer:

1. Option A. Beta decay minus 0 -1e

2. Option B. Alpha 4 2He

3. Option A. Beta decay minus 0 -1e

Explanation:

1. 66 29Cu is undergoing beta decay minus since it produces a daughter nuclei having the same mass number and the atomic number increased by 1 i.e 66 30Zn

2. 238 92U is undergoing alpha decay since the daughter nuclei produced has a decrease of 4 in the mass number and a decrease of 2 in the atomic number ie 234 90Th

3. 14 6C is undergoing beta decay minus since the daughter nuclei produced has the same mass number and the atomic number increased by 1 i.e 14 7N
