A piece of word has a mass of 3.16 g; when placed in 20.0 mL of water, the water volume increased to 23.4 mL. What is the densit
Elza [17]

Answer:

0.93g/mL

Explanation:

Given parameters

Mass of wood  = 3.16g

Initial volume of water  = 20mL

Volume of water + wood  = 23.4mL

Unknown:

Density of the wood  = ?

Solution:

Density is the mass per volume of a substance.

 It is mathematically expressed as;

       Density  = \frac{mass}{volume}

Volume of wood = 23.4mL  - 20mL = 3.4mL

So,

    Density = \frac{3.16}{3.4}   = 0.93g/mL

How many of the following molecules have sp2 hybridization on the central atom? hcn so2 ocl2 xecl2.
GrogVix [38]

Only one molecule have <u>sp2 </u>hybridization on central atom and that is <u>SO₂</u>.

<u>XeCl₂</u> have <u>sp3d </u>hybridization.

<u>OCl₂</u> have <u>sp3 </u>hybridization.

<u>HCN </u>have <u>sp </u>hybridization.

Hybridization is defined as the concept of mixing two atomic orbitals to give rise to a new type of hybridized orbitals.

Hybridization intermixing usually results in the formation of hybrid orbitals having entirely different energies, shapes, etc.

A heterogeneous mixture is a
Sliva [168]
Answer: A heterogeneous mixture is a mixture in which its components retain their identity. Why: Heterogeneous mixtures have several parts which can't be separated, like an italian dressing. Therefore, it's prefix is (hetero), which means something along the lines of "different". In a homogeneous mixture, it can be separated, and the prefix (homo) means "same".

While ALL the information in a Schumer Box is important, which items do you think matter most on a day-to-day basis?
Oksana_A [137]

Answer:

The most important information is: financial charges, annual fees, minimum payments and how the balance is calculated.

Explanation:

A Schumer Box is a table where the credit card companies disclose all the terms and conditions necessary to make a contract with them, as well as disclose all fees, charges, balances and elements that make up the credit card.

All information shown on a Schumer Box is important, but the most important is that which deals directly with the customer's money or balance. This information is: financial charges, annual fees, minimum payments and how the balance is calculated.

Calculate the enthalpy change, ΔH, for the process in which 30.1 g of water is converted from liquid at 10.1 ∘C to vapor at 25.0
gayaneshka [121]
You can split the process in two parts:

1) heating the liquid water from 10.1 °C to 25.0 °C , and

2) vaporization of liquid water at constant temperature of 25.0 °C.


For the first part, you use the formula ΔH = m*Cs*ΔT

ΔH = 30.1g * 4.18 j/(g°C)*(25.0°C - 10.1°C) = 1,874 J

For the second part, you use the formula ΔH = n*ΔHvap

Where n is the number of moles, which is calculated using the mass and the molar mass of the water:

n = mass / [molar mass] = 30.1 g / 18.0 g/mol = 1.67 mol

=> ΔH = 1.67 mol * 44,000 J / mol = 73,480 J

3) The enthalpy change of the process is the sum of both changes:

ΔH total =  1,874 J + 73,480 J = 75,354 J

Answer: 75,354 J
