The four metals that will not replace hydrogen in an acid are Cu, Ag, Au, Hg.

Explanation:

As Copper Cu lies below the hydrogen, this is why it is less reactive and ca not replace Hydrogen from its compound.

Silver Ag also lies below the hydrogen and therefore it is less reactive to displace Hydrogen.

Gold Au becomes less reactive than Hydrogen due to its placement below Hydrogen acid.

Mercury Hg is less reactive than Hydrogen

66 mph

Explanation:

Average speed is the rate of change of distance with time:

Average speed = $\frac{Distance }{time}$

Given parameters:

Starting point = 88mile marker

End of journey = 121mile marker

time = 30minutes = 0.5hr(60min = 1hr)

Solution:

The distance covered in this journey:

Distance = End of journey - starting point = 121 mile - 88 mile = 33mile

Average speed = $\frac{33miles}{0.5hr}$

= 66mph

The average speed of Sara's mum is 66mph

A neutral atom of Cl-37 has

Ostrovityanka [42]

Answer:

17 protons, 20 neutrons, and 17 electrons.

Explanation:

A periodic table can be defined as the standard arrangement of chemical elements by atomic number, electronic configuration and chemical properties in a tabular form.

Generally, a proper representation of the mass number and atomic number of chemical elements is key and very important in chemistry.

Furthermore, as a rule, it should be noted that the mass number (nucleon number) is always larger than the atomic number(number of proton).

The mass number of this neutral atom of Cl-37 is 37 and we know that the atomic number (number of protons) of chlorine is 17. Also, the atomic number of an element is equal to the number of its electrons.

A neutral atom of Cl-37 has 17 protons, 20 neutrons, and 17 electrons.

Hence, a neutral atom of Cl-37 can be identified based on its number of protons because it represent its atomic number, which is what is used to differentiate an atom of an element from the atom of another chemical element.

Density = 11g/cm3 volume = 2cm3 what is the mass

jolli1 [7]

<h2>Question:-</h2>

Density = 11g/cm³, volume = 2cm³. What is the mass ?

<h2>Solution:-</h2>

We know,

${ \boxed{\bf{\rm \red {Mass \: = \: Density \: × \: Volume}}}}$

So, Mass = 11g/cm³ × 2cm³

Mass = 22 g

<h3>The mass is 22 g. [Answer]</h3>
