Answer:
8.90
Explanation:
Density = mass ÷ volume
D = 222.50 g ÷ 25.00
= 8.9
The density of the unknown metal is 8.90.
Hope that helps.
<span>It is known
that acids compounds contains hydrogen and produces hydrogen ion in water. A binary
acid however is an acid that have two elements, one of the element has a
hydrogen attached to it. Examples of binary acids are hydrogen fluoride (HF),
hydrogen bromide (HBr) and hydrogen sulfide (H2S). In naming a binary acid, it
has two rules; one, as pure compounds and two, as acid solutions. For pure
compounds, start with the name ‘hydrogen’ and end the anion name with ‘-ide’. For
acidic compounds, start with ‘hydro-‘, end the anion with ‘-ic’ and add ‘acid’.</span>
It speeds up chemical reactions
Away from you. This is known as the Doppler affect. It basically states that if an object is moving away from you the streching of the wave causes a red shift and if the object is moving towards you the compression of the waves causes a blue shift.
Answer:
<u>False</u>
Explanation:
- The carbon cycle is a process which involves the flow of carbon through all of living things and life forms on Earth. The carbon cycle span over two segments: long-term and short-term, allowing for regulation of atmospheric carbon dioxide.
- While the short term segment deals with Earth forms that are more 'fleeting' like water nd air, the long-term affects the rock which take centuries to process through completely.
- In the short-term reservoir, carbon is stored in the atmosphere, oceans and biosphere with the ocean containing the largest amount of carbon. The biggest player and regulator of atmospheric carbon however is the ocean, not the biosphere. It is what links the long-term segment reserves to the short-term because carbon dioxide is removed from the atmosphere and converted to fossil fuels and rocks which are components of the long-term reserves.
I hope this explanation was clear and comprehensive.
