Answer:
6CO2 + 6H20 + ENERGY = C6H12O6 + 6O2
Explanation:
Carbon dioxide + water + energy from light produces glucose and oxygen

A block has a density of 1.73 g/mL has a density of 1.73 * 10⁶ mg/L.
<h3>What is density of a substance?</h3>
The density of a substance is the ratio of the mass of a a given volume of a substance and the volume of that substance.
Mathematically, the density of a substance is given by the formula shown below:
- Density = mass of substance/volume of substance.
Depending on the units in which the mass and volume of the substance is given, the unit of density can be given as follows:
kilogram per cubic meter; kg/m³
gram per cubic centimeter; g/cm³
gram per liter; g/L
milligram per liter; mg/L
The given block has a density of 1.73 g/mL.
To convert from gram to mg, we multiply by 1000
1.73 g = 1.73 * 1000 = 1730 mg
to convert from mL to L, we divide by 1000
1 mL = 0.001 L
Density of the block in mg/L = 1730 mg/ 0.001 L
Density of the block in mg/L = 1.73 * 10⁶ mg/L

Answer:
Newton's first law.
Explanation:
It is the same as law of inertia.
In order to get the sum of 2.7 and 2.47, we will add both numbers. So, 2.7 plus 2.47 would be 5.17. And the correct number of significant digits in this number is still the same, 5.17, so we have three significant numbers. Why? There are three rules in identifying the significant figures: 1. Non zeros are always significant (which this applies in our sum above). 2. Any zeros in between significant numbers are always significant. 3. <span> The final zero or zeros in the decimal portion only are significant.</span>
