An atom has an average atomic mass of about 63.5 amu. What is the chemical symbol for the atom? Consult the periodic table.
bearhunter [10]
An atom has an average atomic mass of about 63.5 amu. 
<span>
1 amu is equal to 1 gram per mole

so 63.5 amu is just equal to 63.5 grams per mole or 63.5 g/mol
the answer is Cu or copper.

xenn [34]

Answer:

See the complete question and the answer below

Explanation:

Sam and joe are trying to determine whether their ideas are scientific or pseudoscientific. sam's idea is not rejected when experiments produce different results. joe's idea gives the same result when tested repeatedly.  which statement is correct about sam and joe's idea?

<em>both ideas could be scientific. </em>

<em>neither idea could be scientific. </em>

<em>only sam's idea could be scientific. </em>

<em>only joe's idea could be scientific.</em>

<em />

The correct answer here would be that both ideas could scientific.

Scientific ideas are those that hold true or not rejected after being tested by different experiments. Pseudoscientific ideas cannot hold true after being tested by experiments.

If an idea is tested by repeated experiments and the experiments produce different results, the idea might remain unrejected if there are no overwhelming evidence to do so from the experiments. That an idea remains unrejected due to inadequate experimental evidence, however, does not mean it is scientific or unscientific.

In the same vein, that a repeatedly tested idea gives the same results does not mean that the idea is scientific unless the results say so. If results repeatedly go against the idea, it means such an idea is unscientific or pseudoscientific.

<em>Hence, both Joe and Sam's idea could be scientific, provided further experimental investigations are carried out.</em>

Which compound would you expect to be least soluble in water? Explain.
Sophie [7]

Answer:  a.CCl4 aka carbon tetrachloride

Explanation:

ionic compounds and polar molecules can be dissolved in water which is a polar solvent.

choice d (KF) is a salt (an ionic compound) and can be dissolved in water /(K+ and F- ions would be formed in water).

choice c (NH3 or ammonia) is a very polar molecule and thus can be dissolved in water(Hydrogen bonding).

choice b (CH3Cl) is slightly polar because the atoms surrounding the central carbon atom are different(3 H atoms and 1 chlorine atom) and can be dissolved in water(Dipole-dipole interaction).

choice a is nonpolar and cannot be dissolved in water.
