Answer:
look at the photo........................
The two properties which are used to define matter are that it has mass
and it takes up space. The other properties do not necessarily apply to
each matter. Such some matter can be a conductor of heat (such as metal)
and some not (such as non metals). Likewise, some matter can be buoyant
and float on liquid of density more than it but others would not on the
liquids of density less than it. In-fact not all the matters are
conductors of energy (such as heat, sound, electricity) or at-least a
very poor conductor of energy and tend to find application as
insulating agents (non conductors). So the only thing which is
necessarily true is that the matter would definitely have mass in even
their minutest form as atom and would take up some space.
Answer:
The correct option is: Recency effect
Explanation:
Serial position effect is a concept that describes the <u>effect of the position of an item in a sequence on its recall accuracy</u>. According to this theory, in a sufficiently long list of items, an individual is more likely to recall the first and the last items with greater accuracy than the middle items.
There are two types:
<u>1. Recency effect</u>: <u>The items in the end of the list or series are recalled first and more accurately.</u>
<u>2. Primacy effect</u>: The items in the beginning of the list or series are recalled first and more accurately.
In the given example, Jaden can only recall the abbreviation for the <u>last 5 elements in a list of 30 elements</u>. This tendency is known as Recency effect.
How many grams of Cu would be needed to react with 2.0 mol HNO3?
<span>by the equation </span>
<span>3Cu + 8HNO3 --> 3Cu(NO3)2 + 2NO + 4H2O </span>
<span>2.0 mol HNO3 reacts with 3/8 ths as many moles of Cu = 0.75 moles of Cu </span>
I think its b or a
i hope i help
