The system schema goes person<string<cart

Then beneth that place earth and dram arrows pointing at person and cart because they r the only ones touching the earth. I do not know what the force diagram would look like so please dont ask

The mass of calcium phosphate the reaction can produce is <u>6.076</u> grams.

Mass is a numerical measure of inertia, which is a basic feature of all matter. It is, in effect, a body of matter's resistance to a change in speed or position caused by the application of a force.

In the International System of Units (SI), the kilogram is the unit of mass.

Given;

Mass of calcium nitrate (Ca(NO₃)₂) = 96.1 g

Mass of calcium phosphate=?

The chemical equation is found as;

3Ca(NO₃)₂ + 2Na₃PO₄ → 6NaNO₃ + Ca₃(PO4)₂

3 moles of Ca(NO₃)₂ produces 1 mole of Ca₃(PO4)molar mass of calcium phosphate is 164 g/mol

Moles are found as the ratio of the mass of the compound and its molar mass. Moles of Ca(NO₃)₂ is n.

n = 96.1/164 = 0.5859 moles

Moles of Ca3(PO4)2 produced ;

N=0.0589 ×(1/3) = 0.0196 moles

The molar mass of calcium phosphate is 310 g/mol and the mass of calcium phosphate produced will be;

M=0.0196×310

M = 6.076 g

Hence,the mass of calcium phosphate the reaction can produce is <u>6.076</u> grams.

To cook food, a microwave oven converts electrical energy intoenergy A) electromagnetic B) heat C) mechanical D) nuclear

Romashka-Z-Leto [24]

To cook food, a microwave oven converts electrical energy into electromagnetic energy. (A) Specifically, it pours high-power RADIO waves into the box.

Water molecules and fat molecules resonate (jiggle) with the radio waves, and the heat is generated IN THE FOOD.

I work with microwave radios.

-- To communicate high-speed data over a distance of 5 to 10 miles, we use a radio transmitter with a power output of 0.07 watt .

-- To communicate high-speed data over distances up to 80 miles, we use a radio transmitter with a power output of 1 to 2 watts.

-- To heat up a chunk of leftover meatloaf, a microwave oven pumps radio waves into the box with a power output of 1200 to 1500 watts ! !
