Answer:
Pressure is the perpendicular force applied per unit area.
<h3><u>Answer;</u></h3>
A: by counting up each individual atom and make sure the atom numbers are the same in the reactants and the products
<h3><u>Explanation;</u></h3>
- <em><u>According to the law of conservation of mass, the mass of reactants should always be the same as the mass of the products in a chemical equation. </u></em>Therefore, <em><u>the number of atoms of each element in a chemical equation should always be the same on both sides of the equation, </u></em>that is the side of reactants and side of products.
- Thus, <em><u>any chemical equation requires balancing to ensure that the number of atoms of each element is equal in both sides of the equation</u></em>. Balancing is a try and error process that ensures that the law of conservation of mass holds.
- In this case, the balanced equation would be; 2Na +2H₂O → 2NaOH +H₂
Answer:
d = (3 i + 5 j) 3 [m] x-distance and 5 [m] y-distance
Explanation:
We can find the displacement if we use a diagram with the cartesian coordinates of the displacement of the mouse.
In the attached image we can see each of the vectors and the origin where the mouse was in the initial position and then the final position after the mouse moved to the right.
So the mouse moved 3 meters to the right and 5 meter upward.
<span>The correct option is: (A) 41 °F (5°C)
Explanation:
As the temperature increases (from 6-7 °C), the tendency of a bacteria to grow also increases. Therefore, it is recommended to keep the temperature of refrigeration units, salad bars and other cold items at 41 °F (5 °C) or colder. Hence, the correct answer is option (A).</span>
