<span>chemicals reacting are written on the left, what is formed is written on the right after the = sign
eg Copper + oxygen = copper oxide.
Hope this helps , mark as brainliest and say thanks THANKS..</span>
Answer:
unsaturated
Explanation:
All solutions have a definite capacity of dissolving solute in it.
Unsaturated solutions are the solutions which contain less amount of solute than the maximum capacity of dissolving the solute. If more amount of solute is added in such a way a point is reached where addition of more solute cannot be dissolved. The solution is known as saturated solution.
Amount dissolved > Maximum solubility limit, the solution is saturated.
Amount dissolved < Maximum solubility limit, the solution is unsaturated.
If the amount of the salt exceeds the solubility limit, then the solution is saturated solution. If it is less than the limit given, then it is unsaturated solution.
The solubility = 0.667 grams per liter
Amount dissolved = 0.502 grams per liter
Since,
Amount dissolved < Maximum solubility limit, the solution is unsaturated.
Answer: metabolic acidosis.
Explanation:
Anion Gap(AG) is the difference between positively charged ions and negatively charged ions. It is usually expressed in milliequivalents per litre of millimoles per litres.
Anion Gap is measured or calculated when there is a need to know the cause of metabolic acidosis. To
Anion Gap can be calculated with or without potassium.
(1). With potassium= ([Na^+] + [K^+]) − ([Cl^−] + [HCO^−3]).
From the question; client's lab values are sodium 166 mEq/L, potassium 5.0 mEq/L, chloride 115 mEq/L, and bicarbonate 35 mEq/L.
Slotting in the values, we have;
==>[ (166+5) - (115+35)] mEq/L.
(2). Without potassium:
==> [Na^+] - ([Cl^−] + [HCO^−3]).
==> [(166) - 115 + (35)] mEq/L
Normal Anion gap is 20 mEq/L(Calculating with Potassium) and 8-16 mEq/L (calculating without potassium).
molarity =Number of moles of compound*1000/(mass of solvent)
Number of moles of NaCl=Given mass/molar mass
Given mass of NaCl=14.3 g
molar mass of NaCl=58.44g
Number of moles of NaCl= 14.3/58.44
=0.244
Mass of solvent (Water)=42.2 g
Molarity=0.244*1000/(42.2)
= 5.80m
Answer:
- You may normally expect a <em>slow</em> reaction if a <em>high</em> activation energy is required.
- Or, You may normally expect a <em>fast</em> reaction if a <em>low</em> activation energy is required.
Explanation:
- To answer this question, we should define firstly the term of activation energy.
- The activation energy is the minimum energy must the reacting molecules have to initiate the chemical reaction.
- Also, we can define it as The energy barrier that the molecules must posses an amount of energy equal or more than the value of this barrier.
- So, as the activation energy be of low value, the possibility that the reacting molecules can have this amount of energy to initiate and proceed the reaction increases and the reaction rate also increases.
- Additionally, as the activation energy be of high value, the possibility that the reacting molecules can have this amount of energy to initiate and proceed the reaction decreases and the reaction rate also decreases.
Thus, we can answer this question as:
- You may normally expect a <em>slow</em> reaction if a <em>high</em> activation energy is required.
- You may normally expect a <em>fast</em> reaction if a <em>low</em> activation energy is required.
