Answer:
Medication
Explanation:
These pharmaceuticals can pollute our water and unintentionally expose us to the chemicals in these medications. Recent studies have found that medicines flushed down the drain can contaminate our lakes and streams, which can hurt fish and other aquatic wildlife, and end up in our drinking water.
Answer:
Pulse
Explanation:
The sign that would make me call 911 is his pulse. If the child's pulse is unresponsive, then that would be a clear sign for me to call the paramedics.
Answer:
48.6 g
Explanation:
Given data:
Length of one side = 3 cm
Density of cube = 8.1 g/cm³
Mass of cube = ?
Solution:
First of all we will calculate the volume of cube.
V = length × height × width
V = 3 cm × 3cm× 3cm
V = 27cm³
Now we will determine the mass by using density formula.
d = m/v
d = density
m = mass
v = volume
8.1 g/cm³ = m/ 27 cm³
m = 8.1 g/cm³ ×27 cm³
m = 48.6 g
Answer:Hence, the bond length in HCl is 125 pm.
Explanation:
Bond length : It is an average distance between the nuclei of two bonded atoms in a molecule.
Also given that bond length is the distance between the centers of two bonded atoms. on the potential energy curve, the bond length is the inter-nuclear distance between the two atoms when the potential energy of the system reaches its lowest value. Beyond this if atoms come closer to each other then their will be repulsion between them.
So, the bond length between the Hydrogen and Chlorine atom in HCl molecule is :
Hence, the bond length in HCl is 125 pm.
