Answer:
Element with the smallest radius is Carbon.
Explanation:
In a periodic table, atomic radius increases down the group due to addition of a new shell and decreases across the period from left to right due to increasing nuclear charge.
Due to addition of more electrons in same shell and increase of positive charge in nucleus increases attractive forces between electrons and nucleus hence decreasing size.
Carbon and Lithium are present in same period and hence Carbon has smaller size; Potassium and Bromine are present in same period and hence out of the two, Bromine has smaller size.
On comparing Carbon and Bromine, atomic radius increases down the group hence, Carbon has the smallest radius among the four given elements.
pretty sure its A
water being boiled in a pot shows a phase change from liquid water to gaseous water when it evaporates
all other choices are just changing its form or shape basically, solid to solid
The total weight of both objects : 7.035 x 10⁻⁸ kg
<h3>Further explanation</h3>
Given
The weight of a grain of sand : 3.5 x 10⁻¹⁰ kg
The weight of one hair from his eyebrow : 7 x 10⁻⁸ kg
Required
The total weight of both objects
Solution
Scientific Notation consists of 2 parts
1. the first part: the first digit followed by the decimal point
2. The second part: the power of 10 (the exponents).which shows the number of digits after the decimal point
To add/subtract, the exponents must be the same and then add/subtract the coefficient
- convert the largest exponent (7 x 10⁻⁸)
7 x 10⁻⁸ = 700 x 10⁻¹⁰
Answer and Explanation:
Elisa is feeling tired because she has diabetes - suported: diabetes, in fact, can trigger episodes of extreme tiredness in patients, this tiredness may have been accompanied by dizziness and being.
Elisa is feeling tired because she has anemia. - Supported: Anemia hampers the transmission of oxygen in the blood, which can cause tiredness, weakness and extreme fatigue.
Elisa is feeling tired because she has an injury to her pancreas - suported: The pancreas is responsible for the production of insulin which is essential to prevent diabetes from establishing itself in the body. If the pancreas is damaged, insulin may be insufficiently produced, increasing the chance of developing diabetes and causing tiredness.
Elisa is feeling tired because she has asthma - suported: asthma causes breathing difficulties, this can cause tiredness and fatigue.
