Answer:

lewis from stardew valley or who?

Explanation:

Answer:

Explanation:

Answer:

No, because the number of carbon, hydrogen & oxygen atoms on both sides of the equation are not equal.

Explanation:

For an equation to be completely balanced, there should be equal number of reactants and products.

Number of carbon atoms on reactant side = 16

Number of hydrogen atoms on reactant side = 16

Number of oxygen atoms on reactant side = 50

Number of carbon atoms on product side = 8

Number of hydrogen atoms on product side = 36

Number of oxygen atoms on product side = 34

Therefore, we can conclude that total number of reactants does not equal total number of products therefore, this equation is not completely balanced.

Answer: hatred and holes

Explanation: this basically is saying that you need to put god first and not let your hate grow or fester inside of you. By filling your holes(from tragic or life changing events) with god, instead of hate or anger, you are giving your life a better outcome.2 Corinthians 1:20 is implying that you need to put your faith in god and believe in him, if you do this, than anything is possible because your spirit is filled with his love and grace.

The amount of heat released is 45.89kj.

The process involved in the reaction are

1.H20(314k)

2. H20 in solid form at 263k

Q= [m×Cpl ×Tfinal -Tinitial) + ∆H fussion

Q= amount of heat released = ?

m = mass of water = 27 g

cp(l) = specific heat of liquid water = 4.184 J/gk

Cp(s) = specific heat of solid water = 2.093 J/gk

∆H fussion = enthalpy change for fusion = 40.7 KJ/mole = 40700 J/mole.

Therefore, Q= 27 × 4.184j/gk × (314-2173k) + 40700j + (27g × 2.093j/gk ×273-263k).

Q = 45896.798j

Therefore, 1kj is 1000j

Therefore, the amount of heat released is 45.89kj.

Explanation:

Solid have the unique shape and low temperature, plasma have not unique shape and high velocity and both show electrical conductivity.

Matter is divided into 4 states as solid, liquid, gas and plasma according to the arrangement of atoms present in that.

In the solid state all particles are connected rigidly with each other, and show very less movement that's why maintain a unique structure. They have low temperature as it helps to maintain the rigidity and it also conducts electricity because of the presence of electrons in the constitute atoms.

This is the 4th state of matter in which positively and negatively charged particles are present, these particles are held together by the weak force that's why they show good velocity, and do not maintain a unique shape. Plasma also shows the electric conductivity.

Hence, both state will conduct electricity and show different characteristics.

Answer:

V2 = 1.14

Explanation:

V1 = 1.2L

P1 = 720 torr (÷ by 760 to get atm. Because 1 atm equal 760 torr) = 0.95 atm

P2 = 1 atm

V2 =?

Follow the equation below to solve this question

P1V1 = P2V2

0.95 x 1.2 = 1 x V2

1.14 = V2

So 1.14 is the answer!

The four acids will require the same volume of the base to reach the equivalence point.

Strong acids completely ionize in waters while weak acids are only partially ionized in waters.

At 0.5 M concentration, the hydrogen ion concentrations of all four acids would be the same.

This means that each of the acids will require an equal volume of base concentration in order to get neutralized.

574 grams of NaNO₃ is needed to make 4.50 L of a 1.50 M NaNO₃ solution.

Mass of any substance will be calculated from moles as:
n = W/M, where

W = required mass

M = molar mass

First we calculate the moles of NaNO₃ from molarity as:

n = M × V, where

M = molarity of NaNO₃ = 1.50 M

V= volume of NaNO₃ = 4.50 L

Moles of NaNO₃ = 1.50 × 4.50 = 6.75 moles

Given molar mass of NaNO₃ = 85 g/mole

Now we calculate all these values on the above equation and calculate the required mass of NaNO₃ as:

W = 6.75 × 85 = 573.75 g or 574 grams

Hence, 574 grams is the required mass of NaNO₃.

Explanation:

For the given chemical reaction, NH₄ - NH₃ and H₂O - H₃O is the acid - conjugate base pair.

An acid - conjugate base pair are those pairs which are differ by the only one proton or H⁺ ion.

Given chemical reaction is:

NH₄ + H₂O → NH₃ + H₃O

According to the Bronsted-Lowry theory, acids are those which gives H⁺ ion and bases are those which accept H⁺ ion in the aqueous solution. In the above reaction NH₄ is an acid as it losses H⁺ ion and NH₃ is the conjugate base of NH₄. Similarly, H₂O is a base as it accepts H⁺ ion and H₃O is the conjugate acid of H₂O.

Hence, NH₄ - NH₃ and H₂O - H₃O is the acid - conjugate base pair.

P= 84.56 %

Question Parameters:

A Grignard synthesis begins with 6.00 g

and ends with 3.94 g benzoic acid.

Generally, if 157 g of bromobenzene produced = 122 g of benzoic acid

Hence,6 g of bromobenzene will produce

X== (122 / 157 ) * 6

X= 4.66 g

Since the experimental yield of benzoic acid = 3.94 g

Therefore the Percentage yield

P = 3.94 / 4.66  * 100

P= 84.56 %
