ok :)
Explanation: genetically modified organisms (GMOs) are being made by inserting a gene from an external source such as viruses, bacteria, animals or plants (etc) into foods. Genetically modified foods seem to be not as healthy as unmodified foods, according to research. also many people are against it due to the fact that some people go overboard and add too many genetically modified organisms, which causes health risks and unfortunately harms people. sometimes genetically modified food contains toxins and antibiotics. srry i couldnt find much on the process but this is based off my background knowledge so yeah
Answer:
C
Explanation:
2 N on left so we put a 2 on the right which makes 6 H so we need 6H on the left to do that we add a coef. of 3 to make 6 H and balance the equation
Answer:
The answer to your question is 175 gallons
Explanation:
Data
60% antifreeze solution volume = ? = x
25% antifreeze solution volume = 25%
Final concentration 50%
Process
0.6x + 0.25(70) = 0.5(70 + x)
Simplification
0.6x + 17.5 = 35 + 0.5x
0.6x - 0.5x = 35 - 17.5
0.1x = 17.5
x = 17.5/0.1
Result
x = 175 gallons
Mass percent is the estimation of the mass of the element in a compound in percentage form. The mass % of manganese (Mn) in potassium permanganate is 34.76 %.
<h3>What is the mass percentage?</h3>
The mass percentage is defined by dividing the mass of the element by the molecular mass of the compound followed by multiplying it by 100%. It is given as,
Mass % = (Atomic Mass of element ÷ Molecular Mass) × 100
As it is known that,
Atomic Mass of manganese = 54.94 g/mol
Molecular Mass of potassium permanganate = 158.034 g/mol
Substituting values to calculate mass % as:
% Mn = (Atomic Mass of Mn ÷ Molecular Mass of KMnO₄) × 100
= (54.94 g/mol ÷ 158.034 g/mol) × 100
= 34.76 %
Therefore, 34.76% Mn is present in KMnO₄.
