Answer:

Physical

Explanation:

because the erosion of the canyon did not change any of the chemical attributes of the rock it only changed the appearance. it may have changed the color which is an example of chemical properties but in this case, it is physical. But in other cases, you would refer to this type of weathering as mechanical weathering.

When solid Ni metal is put into an aqueous solution of Pb(NO3)2, solid Pb metal and a solution of Ni(NO3)2 result. Write the net
Sonja [21]

Answer:

Pb^{2+}(aq)+Ni(s)\rightarrow Ni^{2+}(aq)+Pb(s)

Explanation:

Hello there!

In this case, according to the given information, it turns out firstly necessary for us to write the complete molecular equation as shown below:

Pb(NO_3)_2(aq)+Ni(s)\rightarrow Ni(NO_3)_2(aq)+Pb(s)

Now, we can separate the nitrates in ions as they are aqueous to obtain:

Pb^{2+}(aq)+2(NO_3)^-(aq)+Ni(s)\rightarrow Ni^{2+}(aq)+2(NO_3)^-(aq)+Pb(s)

And then, we cancel out the nitrate ions as the spectator ones, for us to obtain the net ionic equation:

Pb^{2+}(aq)+Ni(s)\rightarrow Ni^{2+}(aq)+Pb(s)

Best regards!

How many kilometers can the car travel on the amount of gasoline that would fit in a soda can? The volume of a soda can is 355 m
g100num [7]
I'll assume that the car is a Honda Insight with <span>EPA gas mileage rating of 57mi/gal in the city.

First, we will convert all units into Km and mL:
1 mile = </span><span>1.609344 Km
</span><span>1gal = 3785.411 mL
</span>
Then, we will calculate the distance the car can move by multiplying the mileage rating and the the volume available as follows (note that I will be converting units in the same step):
distance = <span>(57mi/gal) x (1.609344 km/1mi) x (1gal/3785.411mL) x 355mL 
               = 8.6027 Km</span>

Gold has a density of 19.3g/cm3. If you have a gold bar with a volume of
marin [14]

Answer:

The answer is

<h2>877 g</h2>

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

<h3>mass = Density × volume</h3>

From the question

density = 19.3 g/cm³

volume = 44.9 cm³

The mass of the gold bar

mass = 19.3 × 44.9 = 866.57

We have the final answer as

<h3>877 g</h3>

Hope this helps you
