The density of ice is 920 kg/m³ and that of water is 1000 kg/m³ calculate the relative density​

Chemistry

STatiana [176]2 years ago

When the density of ice is 920 kg/m³ and that of water is 1000 kg/m³ then the relative density​ will be 0.92 kg/m³​

The ratio of a substance's density to given reference material is known as its relative density. For gases, the reference is air at room temperature, but relative gravity for liquids is almost often calculated in relation to the densest possible form of water.

RD= ρ substance/ρ reference

ρ substance = the density of the substance = 920 kg/m³

ρ water = the density of water at 4.0°C, 1000 kg/m3

RD = 920/1000 kg/m³

RD= 0.92kg/m³

Phosphorous +Dilute hydrochloric acid
butalik [34]

Phosphorus trichloride is the precursor to organophosphorus compounds that contain one or more P(III) atoms, most notably phosphites and phosphonates. ... PCl3 reacts vigorously with water to form phosphorous acid, H3PO3 and HCl: PCl3 + 3 H2O → H3PO3 + 3 HCl.

How many grams of ice at -13 deg C must be added to 711 grams of water that is initially at a temperature of 87 deg C to produce
Basile [38]

Answer:

The answer to your question is m = 4.7 kg

Explanation:

Data

Ice                                   Water

mass = ?                          mass = 711 g

T₁ = -13°C                         T₁ = 87°C

T₂ = 10°C                         T₂ = 10°C

Ch = 2090 J/kg°K          Cw = 4180 J/kg°K

Process

1.- Convert temperature to kelvin

T₁ = 273 + (-13) = 260°K

T₁ water = 87 + 273 = 360 °K

T₂ = 10 + 273 = 283°K

2.- Write the equation of interchange of heat

                 - Heat lost = Heat absorbed

               - mwCw(T₂ - T₁) = miCi(T₂ - T₁)

-Substitution

              - 0.711(4180)(10 - 87) = m(2090)(10 - (-13))

- Simplification

                            228842.46 = 48070m

                            m = 228842.46/48070

-Result

                            m = 4.7 kg

How do you explain the relatively high conductivity of tap water compared to a low or zero conductivity for distilled water?
gladu [14]
Tap water contains many dissolved ions that are required to carry an electric current, whilst distilled water contains no or relatively low amounts of dissolved ions. the absence of ions in the distilled water accounts for the low to zero conductivity of the water

hope that helps!
