Pls help!!!!!! In your own words, explain how chemists properly represent the law of conservation of matter in their chemical

Chemistry

WINSTONCH [101]2 years ago

Answer:

They represent it by ensuring that the number of atoms of each element (matter) in the reactant side is the same as the product side

Explanation:

The law of conservation of matter stated that matter can neither be created nor destroyed. Chemical equations involve combining atoms of elements. The compounds combined by chemists are called REACTANTS while the produced compounds are called PRODUCTS.

In order to conform to the law of conservation of matter, the same quantity of matter present in the reactants must be present in the products. This means that the number of atoms of each element (matter) in the reactant side must be the same as the product side. For example;

C6H12O6 + 6O2 → 6CO2 + 6H2O

In this chemical equation for photosynthesis, number of atoms in the reactant side (6 carbon, 12 hydrogen, 18 oxygen) are the same as that in the product side (6 carbon, 12 hydrogen, 18 oxygen), hence, this obeys the law of conservation of mass.

In a nutshell, chemists chemists properly represent the law of conservation of matter in their chemical equations by making sure that same number of atoms of reactants is present in the products.

Why is water able to dissolve salts such as sodium chloride
adell [148]
Water   has  positive  side  and  negative  side. This  is  the  reason  why water  can  dissolve salt  such sodium  chloride.  Example  when  sodium  chloride  dissociate  in  water it  give  Na+  ions  and  Cl- ions. the  negative  side  of  water   attack the  Na+  ions  while  the positive   side  of  water  attract Cl-  ions

Water has a heat of fusion of about 300J/gram and a heat capacity for liquid water of a about 4J/gC. How much heat is needed to
amm1812

Answer:

The total heat required is 3.4 kJ

Explanation:

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

There is a direct proportional relationship between heat and temperature. So, the amount of heat a body receives or transmits is determined by:

Q = c * m * ΔT

where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.

In this case you know;

  • Q= ?
  • c= 4 \frac{J}{g*C}
  • m= 10 g
  • ΔT= Tfinal - Tinitial= 10 C - 0 C= 10 C

Replacing:

Q= 4\frac{J}{g*C} *10 g * 10 C

Solving:

<em>Q1= 400 J</em>

On the other hand, you must determine the heat required to convert 0 ∘ C of ice to 0 ∘ C of liquid water by:

Q2=m*heat of fusion

Q2=10 g* 300 \frac{J}{g}

<em>Q2= 3,000 J</em>

The total heat required is:

Q= Q1 + Q2= 400 J + 3,000 J

Q= 3,400 J= 3.4 kJ (1 kJ= 1,000 J)

<u><em>The total heat required is 3.4 kJ</em></u>

If I have a 78c and I fail a test that’s worth 15% of my grade what would it drop to ?
koban [17]
Depends on the grade of the test. But for the most part if it’s below a 78, it’ll drop, If it’s above it’ll raise. It shouldn’t drop or raise it more than 3 point/percent.

Write the chemical equation for the formation of HI from the single, isolated H and I atoms.
mart [117]

Answer:

H2 + I2 → 2 HI.

Explanation:

Hydrogen iodide is a diatomic gas which can be readily formed from the direct combination of the elements involved which is hydrogen and iodine. Both elements can be combined by irradiating the mixture with an electromagnetic radiation that has a wavelength which is equal to that needed to break the iodine molecule bond between the two iodine atoms

What is the molarity of a solution that has 2.50 moles of NaOH dissolved in 0.500 L of solution?
const2013 [10]

Answer: 5 is the molarity

Explanation:

The molarity formula is moles over liters and that in your case is 2.50 moles divided by .500 L which results in 5 which is your answear hope this helped god bless
