Answer:

Q = 33105.6 J

Explanation:

Given that,

Mass of water, m = 88 grams

The temperature raised from 48°C to steam at 138°.

We need to find the energy required to raise the temperature. The formula for the energy required is given by :

[tex]Q=mc\Delta T[/tex]

Where

c is specific heat of water, c = 4.18J/g °C

So,

[tex]Q=88\times 4.18\times (138-48)\\\\Q=33105.6\ J[/tex]

So, the required energy is 33105.6 J.

Answer:

A

Explanation:

Its a because the temperature is increasing( getting warmer)

Answer:

Atoms of matter are electrically neutral because their nuclei contain the same number of protons as there are electrons surrounding the nuclei. Electric current and charged objects involve the separation of some of the negative charge of neutral atoms.

Answer:

1. Parents from both species.

2. Because of natural selection.

Explanation:

Answer:

Within a group trend

Explanation:

The atomic radius of atoms generally increases from top to bottom within a group trend. As the atomic number increases down a group, there is again an increase in the positive nuclear charge.  As the atomic number increases within a period, the atomic radius decreases.

Answer:

The molecular formula lists the symbol of each element within the compound followed by a number (usually in subscript). The letter and number indicate how many of each type of element are in the compound. If there is only one atom of a particular element, then no number is written after the element.

Answer:

true

Explanation:

All cells have a cell wall. Plant cells are surrounded by a cell membrane and outside this is a fairly rigid cell wall. The cell wall gives the plant cell a more definite shape than an animal cell. Animal cells do not have a cell wall.

Answer:

True

Explanation:

Animal cells don't have any cell walls while plants do

Answer:

34.35 liters

Explanation:

After setting up the formula using the mole map, you would get 1.5 (mol) times 22.4 (liters)

Answer:

1 x 10^-12 mol dm^-3

Explanation:

[H+] = 10 ^ -pH

Therefore, pH 12 = 1 x 10^-12 hydrogen ion concentration

Answer: increasing frequency or energy and decreasing wavelength.

Explanation:

Electromagnetic wave is defined as the wave which is associated with both electrical and magnetic component associated with them. They can travel in vacuum as well and travel with the speed of light i.e  

The electromagnetic spectra consist of radio waves, microwaves, infrared ,Visible , ultraviolet, X rays and gamma rays arranged in order of increasing frequency or increasing energy and decreasing wavelengths.

Answer:

C

Explanation:

I would say C Low Density

SORRY IF I AM WRONG

Carp do take up space, and damage boats, and they are invasive so they dont increase the biodiversity of an area because biodiversity is different species and a variety of species in an area.

The answer is B because the Asian Carp does not increase the biodiversity in an area.

Answer:

[tex]\boxed {\boxed {\sf 5.1 \ mol \ H_2O}}[/tex]

Explanation:

To convert from representative particles to moles, Avogadro's Number: 6.02*10²³, which tells us the number of particles (atoms, molecules, etc.) in 1 mole of a substance.

We can use it in a ratio.

[tex]\frac {6.02*10^{23} \ molecules \ H_2O}{1 \ mol \ H_2O}[/tex]

Multiply by the given number of molecules.

[tex]3.1*10^{24} \ molecules \ H_2O*\frac {6.02*10^{23} \ molecules \ H_2O}{1 \ mol \ H_2O}[/tex]

Flip the ratio so the molecules of water cancel out.

[tex]3.1*10^{24} \ molecules \ H_2O*\frac {1 \ mol \ H_2O}{6.02*10^{23} \ molecules \ H_2O}[/tex]

[tex]3.1*10^{24} *\frac {1 \ mol \ H_2O}{6.02*10^{23} }[/tex]

[tex]\frac {3.1*10^{24} \ mol \ H_2O}{6.02*10^{23} }[/tex]

Divide.

[tex]5.14950166113 \ mol \ H_2O[/tex]

The original number of molecules has 2 significant figures: 3 and 1, so our answer must have the same. For the number we calculated, that is the tenth place. The 4 in the hundredth place tells us to leave the 1.

There are about 5.1 moles of water in 3.1*10²⁴ molecules of water.

Answer:

37 L

Explanation:

Reaction is: 2 Al (s) + 3H₂SO₄(aq) → Al₂(SO₄)₃ (s)  +  3H₂ (g)

2 moles of Al react to 3 moles of sulfuric acid, in order to produce 1 mol of aluminum sulfate and 3 moles of hydrogen.

So ratio between aluminum and hydrogen is 2:3. We assume the acid is the limiting reactant.

2 moles of Al can produce 3 moles of hydrogen

Then 1.1 moles of Al, will produce (3 . 1 .1)/2 = 1.65 moles

If 1 mol of any gas, occupies 22.4L at STP

1.65 moles of H₂ may ocuppy (1.65 . 22.4) / 1 = 36.96 L ≅ 37L

If we had applied Ideal Gases Law → P . V = n . R  .T

At STP. we have 1 atm and 273 K

V = (n . R . T) / P → (1.65 . 0.082 . 273) / 1 = 36.9 L

Explanation:

The genotype for parent is going to be purple flower.

After the crossing is done, we have our p1 to be a purple flower dominant over the the yellow that is to say the parent genotype is going to be a Purple denote a capital P

Answer:

17.64 grams of nitrogen gas will be produced when 0.42 moles of sodium azide decomposes in the automobile airbag.

Explanation:

From the equation of reaction given below:

2 NaN₃ (s) ----> 2 Na (s) + 3 N₂

Two moles of sodium acid will decompose to produce two moles of sodium atom and three moles of nitrogen gas.

Mole ratio of sodium azide to nitrogen gas is 2 : 3

0.42 moles of sodium azide will produce 3/2 × 0.42 moles of nitrogen gas when It decomposes

Moles of of nitrogen gas produced = 0.63 moles

Molar mass of nitrogen gas = 2 × 14 = 28 g

Mass of nitrogen gas produced = 0.63 × 28 g

Mass of nitrogen gas produced = 17.64 g

Therefore, 17.64 grams of nitrogen gas will be produced when 0.42 moles of sodium azide decomposes in the automobile airbag.
