Not sure about any others but I believe 3 goes with B
Answer:
Mass percent of food dyes = 0.0616%
Explanation:
Given data:
Mass of candy = 47.9 g
Calories = 240
Mass of fat = 10 g
Mass of carbohydrate = 34 g
Mass of protein = 2 g
Mass of food dyes = 29.5 mg
Mass percent of food dyes = ?
Solution:
First of all we will convert the mg into g.
Mass of food dyes = 29.5 mg × 1g /1000 mg = 0.0295 g
Mass percent of food dyes = mass of food dyes / total mass× 100
Now we will put the values.
Mass percent of food dyes = 0.0295 g / 47.9 g × 100
Mass percent of food dyes = 0.000616 × 100
Mass percent of food dyes = 0.0616%
Answer:
<h2>1.11 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question we have
We have the final answer as
<h3>1.11 g/mL</h3>
Hope this helps you
The correct answer is d. <span>6H20 + 6CO2.
The reactant in the chemical reaction </span>6H2O + 6CO2 ---> C6H12O6 + 6O2 is 6H20 + 6CO2. Remember that the reactant is always at the left side of the equation. So the correct answer is <span>6H20 + 6CO2 since it's in the left of the equation. I hope this answer helped you. </span>
₈₄²¹⁰Po ⟶ ₈₂²⁰⁶Pb +
Your equation is:
₈₄²¹⁰Po ⟶ ₈₂²⁰⁶Pb + ?
It becomes easier to balance the equation if we replace the "?" with an element symbol _<em>x</em>^<em>y</em>Z.
Then the equation becomes
₈₄²¹⁰Po ⟶ ₈₂²⁰⁶Pb +_<em>x</em>^<em>y</em>Z
The main point to remember in balancing nuclear equations is that the <em>sums of the superscripts and the subscripts</em> must be the same <em>on each side of the equation</em>.
Sum of superscripts: 210 = 206 + <em>y</em>, so <em>y</em> =4.
Sum of subscripts: 84 = 82 + <em>x</em>, so<em> x</em> = 2.
₈₄²¹⁰Po ⟶ ₈₂²⁰⁶Pb +
We should recall that is an <em>α particl</em>e.
Thus, the equation represents the α decay of polonium-210 to lead-206.
The nuclear equation is
₈₄²¹⁰Po ⟶ ₈₂²⁰⁶Pb +
