When there are 165.0grams of reactants, what is the mass of the products for that reaction?
Answers
Answer:
165.0 grams
Explanation:
The law of conservation of mass tells us that the mass of the reactants will be equal to the mass of the products. Therefore, if we begin with 165.0 grams of mass, that is how much there will be at the end in the products, even if it's in different forms.

Answer:
Cl2 + 2NaBr --> 2NaCl + Br2
Explanation:
This is a single displacement reaction where one side of the ionic compound switches with the other.
So, Cl2 + NaBr ---> NaCl + Br2
This isolates the Bromine and puts the Chlorine in it's place.
Then, balance out the equation like so and you should get
Cl2 + 2NaBr --> 2NaCl + Br2

Explanation:
Under each DNA sequence write the complimentary mRNA base sequence that each of these gene fragments would produce. Remember that in the production of mRNA, the DNA base sequence "A" _________________ specifies the RNA base ____________________
Answers
Answer:
The correct answer would be -
Thymine to adenine
Cytosine to guanine
guanine to cytosine
Adenine, and "U" uracil respectively.
Explanation:
mRNA is a sequence of complementary base sequences encoded from a gene or DNA segment which is used to produce the protein by the process called translation.
From converting a sequence from DNA to its complementary mRNA sequence, the rules of complementary base pairing will be applied: Cytosine (C) is replaced with Guanine (G) – and vice versa. Uracil (U) is replaced by Adenine (A) and Thymine is replaced by adenine.
Why are we pulled to the center of the Earth and not into the much larger sun?
Answers
Answer:
The sun's gravity pulls on the earth, and the earth pulls back on the sun at the same time. This is why the center of the solar system is not the center of the sun. As one gravitational body gets bigger than the other, it circles closer to the center of the system (shown in red).
Explanation:
hope this helps...
The earth is known to be falling towards the sun as a result of intense gravity. The earth is known to have plenty of sideways momentum and due to this sideways momentum, the earth is often falling towards the sun and missing it.
The reason we are pulled to the center of the Earth and not into the much larger sun by gravity is that all objects with mass, like our Earth, do bend and curve the fabric of the universe referred to as spacetime.
At most, the gravity from the sun result in our planet moving in a curved, elliptical path. but, the planets are moving fast enough so that they are not pulled into the sun.
The sun has a more weaker gravity and as it loses mass, it causes the Earth to slowly move away from it.

If 1.80 moles of NaCl was dissolved in enough water to make 3.60 L of solution, what is the Molarity?
Answers
Answer:
0.5M
Explanation:
The equation for molarity is:
M = [tex]\frac{mol}{liters}[/tex] ; where the "M" stands for molarity, the "mol" stands for moles of solute and the "liters" means the volume in liters of solution.We are given that there are:
1.80 moles of NaCl (the moles of solute)3.60 Liters of solution (the volume in liters of solution)Now we just plug those numbers into the formula and get our answer:
M= [tex]\frac{1.80mol}{3.60L}[/tex]= 0.5MAfter doing the math and dividing the moles of solute by the liters of solution, we get that the molarity of the solution is 0.5M.
