There won't be any change in the total mass of the atoms involved in a chemical reaction. According to the law of conservation of mass; it states that mass can neither be created nor destroyed in a chemical reaction. So, when atoms participate in a chemical reaction they might displace with other reactants but the total mass will remain the same.

Answer:
3 week or 21 days consume Vitamin C = 19.95 grams
Step-by-step explanation:
given data
orange juice Vitamin C = 0.6 grams
strawberries Vitamin C = 0.35 grams
to find out
How many grams of Vitamin C does Seth consume in 3 weeks
solution
we first find total Vitamin C consume in 1 day that is
total Vitamin C consume in 1 day = orange juice Vitamin C + strawberries Vitamin C
total Vitamin C consume in 1 day = 0.6 + 0.35
total Vitamin C consume in 1 day = 0.95 grams
so
in 3 week have 3 × 7 = 21 days
so in 21 days consume Vitamin C = 1 day consume × no of days consume
21 days consume Vitamin C = 0.95 × 21
21 days consume Vitamin C = 19.95 grams
Answer:
It will take <em>0.75 hours </em>to Russell catch Gertrude
Step-by-step explanation:
<u>Cinematics</u>
The equations of cinematics include velocity, displacement and time. In case only the magnitudes are important, we can use the concepts of speed and distance. The speed can be thought in relative terms, i.e. if one body moves at 10 m/s and other moves at 8 m/s, we can say the relative speed is 2 m/s.
The equation who relates those magnitudes is
The problem states Gertrude travels at 10 mph and is 3 miles ahead of Russell who travels at 14 mph. We want to know the time when Russell will catch Gertrude. Since Russell goes faster than Gertrude, he eventually catches her. In a time t, he must travel 3 miles more than her. Since the relative speed of them is 14-10= 4 mph, we can know the time it takes to the encounter to produce
Answer: It will take 0.75 hours to Russell catch Gertrude
Answer 1:
For problem 1, each shirt can cost $15. Since their are two shirts, the price would equal up to $30. The remaining money can be the price of the athletic shoes, which is $65.
Equation: 15+15+65=95
Answer 2:
For problem 2, the pair of dress slacks can cost $55, the dress shoes can cost $100, and the and the blazer can cost $145.
Equation: 55+100+145=300
The answer is B as from there you can divide each side by 8 and be left with x
