A) MgCl₂(aq)+Na₂CO₃(aq)→MgCO₃(s)+2NaCl(aq)
b) double replacement reaction
c) Yes, Magnesium carbonate forms.
I hope this helps. Let me know if anything is unclear.
<u>No, the captain should continue using the current technology.</u>

<h3>How Nuclear Fusion Reactors Work?</h3>
When hydrogen atoms fuse, the nuclei must come together. However, the protons in each nucleus will tend to repel each other because they have the same charge (positive). If you've ever tried to place two magnets together and felt them push apart from each other, you've experienced this principle firsthand.
To achieve fusion, you need to create special conditions to overcome this tendency. Here are the conditions that make fusion possible:
High temperature gives the hydrogen atoms enough energy to overcome the electrical repulsion between the protons.
- Fusion requires temperatures of about 100 million Kelvin (approximately six times hotter than the sun's core).
- At these temperatures, hydrogen is a plasma, not a gas. Plasma is a high-energy state of matter in which all the electrons are stripped from atoms and move freely about.
- The sun achieves these temperatures by its large mass and the force of gravity compressing this mass in the core. We must use energy from microwaves, lasers and ion particles to achieve these temperatures.
High pressure squeezes the hydrogen atoms together. They must be within 1x10-15 meters of each other to fuse.
- The sun uses its mass and the force of gravity to squeeze hydrogen atoms together in its core.
- We must squeeze hydrogen atoms together by using intense magnetic fields, powerful lasers or ion beams.

Answer:
The rate decreases as the concentration of the reactants decreases.
Explanation:
The measurement of the reaction rate is based on the disappearance of a reactant or appearance of a product with increasing reaction time.
During a reaction, the concentration of a reactant decreases exponentially with time while that of a product increases exponentially with time. This is because a reactant is consumed in a reaction while products builds in that same reaction.
The reaction rate therefore is directly proportional to the concentration of the reactants.
Answer:
a. What would be the expected pH if a Student A accidentally diluted 9.1 mL (instead of 9.0 mL) of the acid to 100 mL? = 2.7423
b. If student A measured the above calculated pH, what would be the resultant K of acetic acid given that they expected the acid to have an initial concentration of 0.18M. = 1.838 x 10 ∧-5

Answer:
14 moles of oxygen needed to produce 12 moles of H2O.
Explanation:
We are given that balance eqaution
We have to find number of moles of O2 needed to produce 12 moles of H2O.
From given equation
We can see that
6 moles of H2O produced by Oxygen =7 moles
1 mole of H2O produced by Oxygen=moles
12 moles of H2O produced by Oxygen=moles
12 moles of H2O produced by Oxygen=moles
12 moles of H2O produced by Oxygen=14 moles
Hence, 14 moles of oxygen needed to produce 12 moles of H2O.
