Answer:
6.28x10⁻³ g
Explanation:
First we convert 0.1102 grams of CoHg(SCN)₄ into moles, using its <em>molar mass</em>:
- 0.1102 g ÷ 491.9 g/mol = 2.24x10⁻⁴ mol CoHg(SCN)₄
There is 1 Co mol per CoHg(SCN)₄ mol, meaning there's also 2.24x10⁻⁴ moles of Co.
We now <u>convert 2.24x10⁻⁴ moles of Co into grams</u>, using its <em>molar mass</em>:
- 2.24x10⁻⁴ mol Co * 28.01 g/mol = 6.28x10⁻³ g
Answer:
The three types of nuclear radiation in increasing order of penetrating power are ____.
alpha, beta, gamma
Explanation:
Alpha Ray: This has the least penetrating power because the particles produced during decay are large in quantity but they have a very low energy which dosent alow them to move far through space because the are ususally blocked.
Beta ray : they have more penetrating power than alpha rays because they a bit higher in energy and quantity {size}
Gamma Ray; this has the most penetrating power. they are highly powerful waves but do little at ionization of other atoms or molecules. it penetrates through molecules very easily due to its size and energy.
Answer:
first number is the correct answer
Answer:
Texture Gradient
Explanation:
Texture Gradient -
It refers to the disrupted pattern on any uniform surface , is referred to as the texture gradient .
The pattern is somewhat very uniform in nature , i.e. , is constant over a particular area .
The three types of texture gradient are-
- perspective ,
- density and
- distortion of texture elements .
Hence , from the given information of the question ,
The correct answer is texture gradient .
