HELP ME IN MY TEST
Answers
Answer:
B - BF3
Explanation:
BF3 has 3 bonds around the central atom and now lone pairs on it. This matches the geometry of a trigonal planar molecule as per the VSEPR Model.
Molecules have two distinct characteristics: form and geometry. Geometry includes the lone pair encircling the focal element whereas shape excludes it. Therefore, the correct option is option B.
What is VSEPR theory?Valence shell electron repulsive force is what VSEPR stands for. Based on the valence electron pairs that are prevalent around the core element of the molecule, the VSEPR theory is employed to predict the structure and geometry of molecules.
According to VSEPR theory, Lone pair lone pair repulsion is greater than bond pair bond pair repulsion. The core atom of BF[tex]_3[/tex] is surrounded by three bonds and contains no lone pairs. According to the VSEPR Model, this corresponds to the geometry of such a trigonal planar molecule.
Therefore, the correct option is option B.

2.
63.9 cm2
3.
63.86 cm2
4.
63.8564 cm2
Answers
Answer:
2.
63.9 cm2
Explanation:
All non-zero digits are consider significant figures like 1, 2, 3, 4, 5, 6, 7, 8, 9.
Leading zeros are not consider as a significant figures. e.g. 0.06 in this number only one significant figure present which is 6.
Zero between the non zero digits are consider significant like 108 consist of three significant figures.
The zeros at the right side e.g 240000 are also significant. There are six significant figures are present.
When we add or subtract the values the number of significant figures after decimal in result must be equal to the given measurement having less number of decimal places. For example,
The difference between 7.69 and 4.0.
7.69 - 4.0 = 3.7
When we multiply or divide the values the number of significant figures must be equal to the less number of significant figures in given value.
For example in given q:
52.6 cm × 1.214 cm = 63.9 cm²

They are in the same family, with similar characteristics.
Their properties change according to a pattern as you go down the column.
Answers
Answer:
They are in the same family, with similar characteristics.
Explanation:
The elements in a given group of the periodic table are in the same family and with similar characteristics.
Vertical columns on the periodic table are referred to as a group or family. Elements having the same number of electrons in the outermost shell of their atoms are placed one another in vertical columns. Each resulting vertical column is a group or family. Elements in the same group exhibit similar chemical properties because of the same number of electrons in their atoms' valence shells.Which refers to a method that relies on sound waves and is used by different animal species for navigation,

An echolocation refers to a method that relies on sound waves and is used by different animal species for navigation, communication, and finding food. Therefore, option A is correct.
What is an echolocation ?Echolocation is a method used by bats, dolphins, and other animals to locate objects using reflected sound. This enables the animals to move around in complete darkness, allowing them to navigate, hunt, recognize friends and enemies, and avoid obstacles.
(1) To hunt for prey, bats make high-frequency sounds. (2) Sound waves are used by dolphins and other toothed whales to locate prey and navigate their surroundings. (3) Nocturnal oil birds use echolocation to navigate their surroundings, particularly in low-light conditions.
Echolocation is used to help with orientation, obstacle avoidance, food acquisition, and social interactions.

An orange falls off of a display at a store and rolls 5 meters in 2.5 seconds the average speed of the orange will be 2 meters per second.
What is speed?Speed if the rate of change of position of an object in a given time of interval or per unit time of interval and it is the ratio of distance traveled to the time taken and the unit will be meter per second.
The average speed of the orange will be if the orange falls off of a display at a store and rolls 5 meters in 2.5 seconds,
Speed = distance / time
Substituting the value,
speed =5 meters /2.5 seconds
speed = 2 meters per second.

Answers
Answer:
4.00 g/mL
Explanation:
Density is mass divided by volume (g/mL).
Mass of rock = 21.58
Volume of rock = 25.4 - 20.0 = 5.4mL
Density of rock = 21.58g / 5.4mL = 3.99629 g/mL

Christy long jump was 51.18inches
2nd Step
we change christy score to cm so we can compare
1 inch = 2.54cm.
therefore 51.18 inches = 51.18 x 2.54= 129.9972cm
Christy won molly by 129.9971cm-118.3cm=11.69 rounded to 12cm
