Answer:

5 mL

Explanation:

Given data:

mass of ring = 107 g

volume of water = 10 mL

increase in volume = 15 mL

How much water displace = ?

Solution:

V (ring) = V (water + ring) - V (water)

V (ring) = 15 mL -  10 mL

V (ring) = 5 mL

when the ring is put into cylinder, volume is increased by 15 mL. The volume of water was 10 mL so water is displaced by 5 mL and the volume 5mL is the voulme of ring.

Answer:

ver explicacion

Explanation:

Los orbitales híbridos se obtienen mediante una combinación de orbitales atómicos.

En un átomo de carbono con hibridación sp3, el átomo de carbono es tetraédrico con un ángulo de enlace de 109,5 grados. Se pueden unir cuatro enlaces simples al átomo de carbono. Se pueden unir un total de cuatro átomos al carbono. Se puede unir un total de cuatro átomos al carbono, lo que ocurre en alcanos como el metano

Para un átomo de carbono con hibridación sp2, hay dos enlaces dobles y dos enlaces simples unidos al átomo de carbono que tiene una geometría plana trigonal con un ángulo de enlace de 120 grados. Se pueden unir un total de dos átomos al carbono. Se pueden unir un total de dos átomos al carbono. Esto ocurre en alquenos como el eteno.

Un átomo de carbono con hibridación sp tiene un ángulo de enlace de 180 grados y tiene una geometría lineal con un enlace triple y un enlace sencillo. Solo se puede unir un átomo al carbono. Esto ocurre en alquinos como el etino.

Iron can be protected from rusting by coating it in a thin layer of zinc in a process called galvanisation.The zinc layer is oxi
lukranit [14]

Answer:

Rusting is an oxidation reaction. The iron reacts with water and oxygen to form hydrated iron (III) oxide, which we see as rust. Here is the word equation for the reaction: iron + water + oxygen → hydrated iron (III) oxide

In this reaction, zinc atoms each will lose two electrons (oxidation) and become Zn 2+ ions. The two electrons that are released by zinc will be gained by the Cu 2+ ions (reduction). The Cu2+ ions become Cu atoms. Total equation: Zn (s) + CuSO 4 (aq) --> Cu (s) + ZnSO 4 (aq)

A student determines the molar mass of a compound by the method used in this experiment. She found the temperature of the ice wa
cluponka [151]

Answer:

139.94 grams of solute is present in  kilograms of water

Explanation:

Temperature of the ice water = T = 1.0°C

Temperature of the mixture = T_f =-3.0°C

Depression in freezing point \Delta T_f=T-T_f

\Delta T_f =1.0°C-( -3.0°C)=4°C

\Delta T_f=k_f\times m=k_f\times \frac{\text{Moles of solute}}{\text{mass of solvent (kg)}}

m = molality of the solution

k_f = Molal depression constant

4^oC=1.86^oC kg/mol\times \frac{\text{Moles of solute}}{0.0793 kg}

Mole of solute = 0.1705 moles

Mass of solute = 11.1 g

Moles of solute = 0.1705 mol=\frac{11.1 g}{M}

Molar mass of the solute= M

M = 65.088 g/mol

Molality of the solution = m = \frac{0.1705 mol}{0.0793 kg}

m\times M=\frac{0.1705 mol}{0.0793 kg}\times 65.088 g/mol=139.94g of solute /kg of water

139.94 grams of solute is present in  kilograms of water
