We first determine the complete reaction of the substances given above to tell whether precipitates are formed.
NaCl + NaBr = no reaction
NaCl + Na2CO3 = no reaction
<span>NaCl + BaCl2 = no reaction</span>
<span>NaCl + HCl = no reaction
</span>
From all the substances given, reaction cannot happen therefore no precipitates are formed.
Answer:
K = 1.08 X 10¹²
Explanation:
The solved solution is in the attach document
D. All of the given statements are true in context of animal cloning.
Explanation:
Cloning is the method in which a similar genetic copy is produced.
Animal cloning is a complex process in which an organism of similar type is produced with same DNA to each other.
Mostly successfully cloned animals in live are cattle,sheep,goats...
Scientists have also cloned rats,mice,rabbits,horses...
This animal cloning is used for farming by the farmers which gives acceleration in their crop production.
Animal cloning have showed some adverse affects in sheep, and other mammal animals regarding issues in their organs like liver,heart,brain etc.
The success rate is very low like 10% in animal cloning due to many reasons such as surviving from birth to the cloned animals.
Probably A, since it’s the only covalent compound. The rest are ionic compounds.
As bracelet is dangling it means there is possibility that the dangled part of bracelet may touch or collide with any lab stuff during performing an experiment
As mentioned in the options the student should remove the dangling bracelet during heating of test tube of acid solution in hot water bath to minimize the chance the bracelet pulling over a test tube, causing a spill.
The acid spill may cause burning , skin irritation, rashes etc
