The correct answer is decomposers.
Answer:
2.7g/cm³
Aluminum
Explanation:
Given parameters:
Mass of the cube = 72.9g
Unknown:
Density of the cube = ?
Solution:
To solve this problem, we need to find the density of the cube. The mass is given and the dimensions of the solid figure.
Now;
Density is the mass per unit volume of a substance
Density =
Volume of the cube = L³ = 3³ = 27cm³
So;
Density = = 2.7g/cm³
The body is aluminum because it has a density of 2.7g/cm³
Answer:
1.5 moles of CO₂ are produced
Explanation:
Based on the chemical equation:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O<em> -The reaction of the question is wrong-</em>
5 moles of oxygen reacts per mole of propane, C₃H₈, to produce 3 moles of CO₂ and 4 moles of water.
If 2.5 moles of oxygen react and, 5 moles of oxygen produce 3 moles of CO₂, moles of CO₂ produced are:
2.5 moles O₂ * (3 moles CO₂ / 5 moles O₂) =
<h3>1.5 moles of CO₂ are produced</h3>
Answer: a,b
Explanation: because a scientific theory is something that been thought of and tested multiple times.
ANSWER: Having low internal demand
EXPLANATION: The economic growth of a country depends upon the goods produced and sold in the country and across borders. If the country is having low internal demands, it will be a loss for the government as there will be less production of goods and services. The government will either have to depend on exports which on one hand have limitations or will have to stop producing goods and services for citizens. This will in turn affect the country in many ways like unemployment, less money circulation etc.
